And the article was included in Bioconjugate Chemistry in 2001.Electric Literature of C7H8INO The following contents are mentioned in the article:

With the goal of developing m-iodobenzylguanidine (MIBG) analogs with improved targeting properties especially for oncol. applications, several radioiodinated ring- and side-chain-substituted MIBG analogs were synthesized. Except for 3-[¹³¹I]iodo-4-nitrobenzylguanidine (I) and N-hydroxy-3-[¹³¹I]iodobenzylguanidine (II), the radioiodinated analogs were prepared at no-carrier-added levels from their resp. tin precursors. The radiochem. yields generally were in the range of 70-90% except for 3-amino-5-[¹³¹I]iodobenzylguanidine for which a radiochem. yield of about 40% was obtained. While the silicon precursor N¹,N²-bis(tert-butyloxycarbonyl)-N¹-(4-nitro-3-trimethylsilylbenzyl)guanidine did not yield 3-[¹³¹I]iodo-4-nitrobenzylguanidine, its deprotected derivative, N¹-(4-nitro-3-trimethylsilylbenzyl)guanidine was radioiodinated in a modest yield of 20% providing 3-[¹³¹I]iodo-4-nitrobenzylguanidine. Exchange radioiodination of 3-iodo-4-nitrobenzylguanidine gave 3-[¹³¹I]iodo-4-nitrobenzylguanidine in 80% radiochem. yield. No-carrier-added [¹³¹I]NHIBG (III) was prepared from its silicon precursor N¹-hydroxy-N³-(3-trimethylsilylbenzyl)guanidine in 85% radiochem. yield. The paired-label tissue uptake of ¹²⁵I and ¹³¹I activity after injection of [¹²⁵I]MIBG, I, II, and III is provided. This study involved multiple reactions and reactants, such as (3-Amino-5-iodophenyl)methanol (cas: 368435-46-5Electric Literature of C7H8INO).

A convenient N-arylation route for electron-deficient pyridines: The case of π-extended electrochromic phosphaviologens was written by Reus, Christian;Stolar, Monika;Vanderkley, Jeffrey;Nebauer, Johannes;Baumgartner, Thomas. And the article was included in Journal of the American Chemical Society in 2015.Product Details of 139139-80-3 The following contents are mentioned in the article:

A simple and representative procedure for the synthesis of N,N’-diarylated phosphaviologens directly from both electron-rich and electron-poor diaryliodonium salts and 2,7-diazadibenzophosphole oxide is reported. The latter are electron-deficient congeners of the widely utilized N,N’-disubstituted 4,4′-bipyridinium cations, also known as viologens, that proved to be inaccessible by the classical two-step route. The single-step preparation method for phosphaviologens described herein could be extended to genuine viologens but reached its limit when sterically demanding diaryliodonium salts were used. The studied phosphaviologens feature a significantly lowered reduction threshold as compared to all other (phospha)viologens known to date due to the combination of an extended π-system with an electron deficient phosphole core. In addition, a considerably smaller HOMO-LUMO gap was observed due to efficient π-delocalization across the phosphaviologen core, as well as the N-aryl substituents, which was corroborated by quantum chem. calculations Detailed characterizations of the singly reduced radical species by EPR spectroscopy and DFT calculations verified delocalization of the radical over the extended π-system. Finally, to gain deeper insight into the suitability of the new compounds as electroactive and electrochromic materials, multicolored proof-of-concept electrochromic devices were manufactured This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3Product Details of 139139-80-3).

A convenient alumination of functionalized aromatics by using the frustrated Lewis pair Et₃Al and TMPMgCl-LiCl was written by Unsinn, Andreas;Wunderlich, Stefan H.;Jana, Anukul;Karaghiosoff, Konstantin;Knochel, Paul. And the article was included in Chemistry – A European Journal in 2013.Recommanded Product: 371764-70-4 The following contents are mentioned in the article:

A straightforward and efficient alumination of functionalized arenes, in particular, halogenated electron-rich aromatic compounds, with Et₃Al and stoichiometric amounts of frustrated Lewis pair TMPMgCl-LiCl (TMP = 2,2,6,6-tetramethylpiperidyl) as a co-reactant, has been developed. In particular, halogenated electron-rich aromatics can be smoothly functionalized by using the frustrated Lewis pair Et₃Al and TMPMgCl-LiCl. Compared with previously described alumination methods, this procedure avoids extensive cooling and the need for an excess of base. This in situ procedure has proven to be most practical and allows for regio- and chemoselective metalation of a wide range of aromatics with sensitive functional groups (CONEt₂, CO₂Me, CN, OCONMe₂) or halogens (F, Cl, Br, I). The resulting aromatic aluminates, which were characterized by using NMR spectroscopy, were subjected to allylations, acylations, and palladium-catalyzed cross-coupling reactions after transmetalation to zinc. It was shown that the nature of the Zn salt used for transmetalation is crucial. Thus, compared with ZnCl₂ (2 equiv), the use of Zn(OPiv)₂ (2 equiv; OPiv=pivalate) allows the subsequent quenching reactions to be performed with only a slight excess of electrophile (1.2 equiv) and provides interesting functionalized aromatics in good yields. This study involved multiple reactions and reactants, such as 2-Chloro-4-iodobenzonitrile (cas: 371764-70-4Recommanded Product: 371764-70-4).

C(sp³)-H Bond Arylation and Amidation of Si-Bound Methyl Group via Directing Group Strategy was written by Han, Jie-Lian;Qin, Ying;Zhao, Dongbing. And the article was included in ACS Catalysis in 2019.Synthetic Route of C17H18F3IO3S The following contents are mentioned in the article:

Silylmethyl functionalization provides a general and efficient access to diverse organosilanes. The traditional methods for silylmethyl functionalization often involved silylmethylmetals or silylmethyl halides. In recent years, a C-H activation strategy has become one of the most attractive alternatives in organic synthesis. Authors envisioned that the attachment of a coordinating group at silicon of methylsilanes provides the opportunity to modify the silylmethyl group via directed C-H bond functionalization. However, despite employment of silicon tethers bearing a directing group (DG) for C(sp²)-H functionalization has been well established due to the fact that the silicon tethers are easily installable and removable/modifiable, applying this concept toward C(sp³)-H functionalization remains underdeveloped. Herein, authors successfully developed Ir^III/Rh^III-catalyzed C-H bond arylation/amidation of silyl Me group by using directing group strategy, which constitutes the most powerful access to benzylsilanes and amino-substituted silanes. Moreover, they demonstrated that the pyridine directing group on silicon atom can be easily removed, and the starting materials can also be efficiently recovered, which are different from those of pyridine-directed C-H functionalization of C-bound Me group. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Synthetic Route of C17H18F3IO3S).

Decomposition of the salts of p-X-benzenediazonium complexes by 18-crown-6 in p-iodoanisole was written by Eustathopoulos, Helene;Court, Jean;Lambeaux, Claude;Bonnier, Jane Marie. And the article was included in Nouveau Journal de Chimie in 1985.Safety of 1-Iodo-4-(4-nitrophenoxy)benzene The following contents are mentioned in the article:

The decomposition of para-substituted benzenediazonium ions complexed with 18-crown-6 has been studied. Anal. of the reaction products from the thermal decomposition of the complexed diazonium salts in p-iodoanisole solution showed that the nature of the para substituent drastically changed the reaction mechanism. The decomposition of the complex p-nitrobenzenediazonium ion proceeds through a radical pathway. In addition to isomeric (p-nitrophenyl)iodoanisoles, the decomposition affords 2,4′-dimethoxy-5-iodobiphenyl and 5,4′-dimethoxy-2-iodobiphenyl, which result from the attack of p-iodoanisole by p-anisidyl radicals derived from the 4-methoxy-4′-nitrophenyliodinyl radical. 4-Iodo-4′-nitrodiphenyl ether and 4-methoxy-4′-nitrobiphenyl could not be detected; therefore, with a strong electron-withdrawing substituent, the decomposition mechanism is exclusively homolytic. The thermal decomposition of the complexed p-chlorobenzenediazonium salt affords products derived from the reaction of the p-chlorophenyl cation and products derived from the reaction of the p-chlorophenyl radical. At [crown ether]/[p-ClC₆H₄N₂⁺] = 6, the homolysis represents at least 30% of the total decomposition This study involved multiple reactions and reactants, such as 1-Iodo-4-(4-nitrophenoxy)benzene (cas: 21969-05-1Safety of 1-Iodo-4-(4-nitrophenoxy)benzene).

3-Azido-5-(azidomethyl)benzene derivatives are useful compounds for preparing diverse bistriazole compounds and photoaffinity probes for target identification of bioactive compounds To more easily synthesize a diverse range of diazido compounds, a facile method for synthesizing diazido compounds bearing a transformable functional group, such as iodo, bromo, methoxycarbonyl, or cyano group, was developed. This method is based on formal C-H azidation of 1,3-disubstituted benzenes via regioselective borylation followed by deborylative azidation with subsequent transformations, such as that of a one-carbon unit on the benzene ring to an azidomethyl group. The functional groups of the diazido compounds were efficiently transformed to various connecting groups, including carboxy, (succinimidyloxy)carbonyl, hydroxymethyl, formyl, bromomethyl, tosylthiomethyl, ethynyl, diazoacetyl, bromoacetyl, boryl, hydroxy, aminocarbonyl, amino, and isothiocyanato groups, leaving the azido groups untouched. Several diazido building blocks were used to prepare diazido compounds by forming amide, thiourea, and sulfide bonds via conjugation at the connecting groups. These results show that the method described here would facilitate diazido probe syntheses and bistriazole library construction.

The method for copper-catalyzed N-arylation of diverse oxadiazolones I (R¹ = cyclopropyl, Ph, 5-methylthiophen-2-yl, etc.) by diaryliodonium salts R²I⁺(R³)R^4- (R² = Ph, 3-(trifluoromethyl)phenyl, 4-nitrophenyl, etc.; R³ = Ph, 2,4,6-trimethoxyphenyl, 4-bromophenyl, etc.) under mild conditions in high yields (up to 92%) using available CuI as a catalyst was reported. The developed method allows utilizing both sym. and unsym. diaryliodonium salts bearing auxiliary groups such as 2,4,6-trimethoxyphenyl (TMP). The steric effects in aryl moieties determined the chemoselectivity of N- and O-arylation of the 1,2,4-oxadiazol-5(4H)-ones I. Mesityl-substituted diaryliodonium salts demonstrated the high potential as a selective arylation reagent. The structural study suggests that steric accessibility of N-atom in 1,2,4-oxadiazol-5(4H)-ones I impacts the arylation with sterically hindered diaryliodonium salts. The synthetic application of proposed method was also demonstrated on selective arylation of 1,3,4-oxadiazol-2(3H)-ones II and 3-(p-Tolyl)-1,2,4-oxadiazole-5-thiol.

And the article was included in European Journal of Medicinal Chemistry in 2019.Quality Control of 2-Chloro-4-iodobenzonitrile The following contents are mentioned in the article:

Prostate cancer (PC) is the second most common malignancy in men worldwide. Among current therapies, two antiandrogens, Abiraterone Acetate and Enzalutamide (Enza) have become the standard of care for patients with metastatic castration-resistant prostate cancer (mCRPC). Here, the authors designed and synthesized a new series of nonsteroidal compounds deriving from the hybridization of Abiraterone (Abi) and Enzalutamide, among which compound I featuring the diphenylamine scaffold was identified as a potent and cell selective androgen receptor (AR) antagonist. In cell proliferation assays, compound I exhibited better antiproliferative activities than Enzalutamide against AR-overexpressing VCaP cells and 22Rv1 cells bearing H874Y-mutated AR. In addition, I suppressed the activity of AR-F876L mutant that confers resistance to Enzalutamide and efficiently blocked R1881-induced PSA and FKBP5 gene expression. In competitive binding assay, compound I displayed higher binding affinity to AR than Enzalutamide. These results suggest compound I as a potential candidate to treat Enza-resistant CRPC.
