Herein, we report a general and simplified synthesis of fluorophosphonates directly from p-nitrophenylphosphonates. This FP on-demand reaction is mediated by a com. available polymer-supported fluoride reagent that produces a variety (25 examples) of fluorophosphonates in high yields while only requiring reagent filtration for pure fluorophosphonate isolation. This reaction protocol facilitates the rapid profiling of serine hydrolases with diverse and novel sets of activated phosphonates with differential proteome reactivity. Moreover, slight modification of the procedure into a reaction-to-assay format has enabled addnl. screening efficiency.

Herein, two mild methods was reported for the catalytic enantioconvergent synthesis of protected dialkyl carbinamines such as RCHXR¹ [R = i-Bu, n-hexyl, (CH₂)₅F, etc.; R¹ = Et, i-Bu, (CH₂)₂Ph, etc.; X = NHBoc, Phth, NHFmoc, etc.], both of which use a chiral nickel catalyst to couple an alkylzinc reagent with α-phthalimido alkyl chloride or an N-hydroxyphthalimide (NHP) ester of a protected α-amino acid. The methods were versatile, providing dialkyl carbinamine derivatives that bear an array of functional groups. Further, for couplings of NHP esters a one-pot variant wherein the NHP ester was generated in situ, allowing the generation of enantioenriched protected dialkyl carbinamines in one step from com. available amino acid derivatives was also described. The utility of this method by applying it to the efficient catalytic enantioselective synthesis of a range of interesting target mols. was demonstrated.

Cai, Zhi Hong published the artcileEffect of Hydrophobic Side Chain Length on Poly(carbazolyl terphenyl piperidinium) Anion Exchange Membranes, Product Details of C6H13I, the publication is ACS Applied Energy Materials (2022), 5(8), 10165-10176, database is CAplus.

In recent years, with the continuous application of superacid-catalyzed condensation reaction in the preparation of anion exchange membranes (AEMs), a number of AEMs with excellent performance have been designed. Among them, the method to copolymerize two aromatic compounds with piperidone via a superacid-catalyzed reaction to synthesize anionic conducting copolymers has been widely discussed by researchers. Here, we focus on the introduction of poly(N-alkylcarbazole-co-terphenyl N,Nâ€?dimethylpiperidinium) (PCTP-n), which is formed by copolymerizing different chain lengths of N-alkylcarbazole (AHC, n = 2, 4, and 6) and p-terphenyl with 1-methyl-4-piperidone (1M4P). As a result of the high-curvature backbone and hydrophobic flexible side chains, the PCTP-n AEMs show comprehensive performance advantage. Among them, the PCTP-6 membrane, with an ultralow swelling (7.9%) and an excellent OH^– conductivity retention (91.9% in 2 M NaOH at 80 °C after 1080 h), highlights high dimensional stability and alk. resistance. Then, the PCTP-2 membrane displays excellent mech. robustness (EB: 40%, TS: 20 MPa) and a decent OH^– conductivity (134 mS cm^-1 at 80 °C). Furthermore, the PCTP-2-based single cell exhibits a decent power d. of 542 mW cm^-2 under H₂-O₂ condition.

Brahma, Sumana published the artcileEffect of alkyl chain length and temperature on volumetric, acoustic and apparent molar properties of pyrrolidinium based ionic liquids in acetonitrile, COA of Formula: C6H13I, the publication is Journal of Molecular Liquids (2022), 118067, database is CAplus.

Detailed anal. of volumetric and acoustic properties of the dilute solution of ionic liquids (ILs) and acetonitrile play a significant role in the potential engineering field and process design. Moreover, these studies can provide relevant knowledge about the types and scope of the intermol. interactions governed between the solute and solvent. In this work, three iodide based pyrolidium ILs, i.e. 1-butyl-1-Me pyrrolidinium iodide, [BMPY]I and 1-methyl-1-pentyl pyrrolidinium iodide, [PeMPY]I and 1-hexyl-1-Me pyrrolidinium iodide, [HMPY]I were synthesized and studied their d. and sound velocity in acetonitrile as a function of molality in the range of 0.05-0.4 mol·kg^-1 and temperature in the range from 293.15 to 328.15 K at atm. pressure. The impact of chain length of cation and temperature were premeditated by using well-known volumetric and acoustic factors. In addition, by employing the exptl. data, the apparent molar volume (V_φ), apparent molar isentropic compression (K_s,φ), and limiting apparent molar expansion (E^{âˆ?/sup>_φ) were calculated Further, the apparent molar properties at infinite dilution were examined by using Redlich-Mayer type equations. Furthermore, measured and calculated properties have been analyzed to understand the solute-solvent interaction in studied systems. For the studied systems, infinite dilution apparent molar properties were increased with cationic chain length on the ILs, however, decreased with temperature}

Radical-polar crossover reactions of dienylboronates CH₂:CR¹CHCR²Bpin with R⁴I and R³Li are applied to the synthesis of functionalized secondary and tertiary allylboronic esters R⁴CH₂CR¹:CHC²R³Bpin (3a–l, R¹ = H, Me, Et; R² = H, Me; R³ = Bu, s-Bu; R⁴ = fluoroalkyl, NCCMe₂, EtO₂CMe₂). The transition-metal-free three-component coupling uses readily accessible dienylboronate esters as substrates in combination with various sp³/sp² carbon nucleophiles and com. alkyl iodides as radical precursors. In the visible light-initiated radical chain process, two new C-C bonds are formed, and the E-double bond geometry in the product allylboronic esters is controlled with good to excellent selectivity.

Hammoud, Fatima published the artcile5,12-Dialkyl-5,12-dihydroindolo[3,2-a]carbazole-Based Oxime-Esters for LED Photoinitiating Systems and Application on 3D Printing, Application In Synthesis of 638-45-9, the publication is Macromolecular Materials and Engineering (2022), 307(8), 2200082, database is CAplus.

In order to expand the application of oxime-esters (OXEs) and to introduce a one-component photoinitiating system of high performance in visible light photopolymerization, a series of 5,12-dialkyl-5,12-dihydroindolo[3,2-a]carbazole-based oxime-esters with visible light absorption abilities is designed and synthesized. Notably, when irradiated with light-emitting diodes at 405 nm, the proposed structures can undergo a direct cleavage of the NO bond followed by decarboxylation, generating free radicals capable to efficiently initiate free radical photopolymerizations (FRP). Furthermore, the new OXEs showed good thermal initiation abilities and can be used as dual photo and thermal initiators. An interesting structure/reactivity/efficiency relationship can be obtained by comparing the reactivity of the different radicals generated upon photoexcitation at identical chromophore but also by comparing the photoinitiating ability of the hexyl derivatives (1)-(10) with that of Me derivatives (1�-(10� characterized by a lower solubility than the previous series in resins. Chem. mechanisms are studied through different techniques including real-time Fourier transform IR spectroscopy, UVvisible absorption spectroscopy, fluorescence (time-resolved or steady-state) as well as mol. modeling calculations To finish, OXEs are incorporated in new photosensitive 3D printing resins, furnishing 3D objects with a remarkable spatial resolution

Hedidi, Madani published the artcileSynthesis of N-pyridyl azoles using a deprotometalation-iodolysis-N-arylation sequence and evaluation of their antiproliferative activity in melanoma cells, HPLC of Formula: 1331850-50-0, the publication is Tetrahedron (2016), 72(41), 6467-6476, database is CAplus.

N-Arylation of pyrrole with 3-iodo-4-methoxypyridine was studied by copper catalysis under different conditions. The best conditions, that proved to be protocol A (CuI, DMEDA or TMEDA, K₃PO₄, DMF at 110°) and above all protocol B (Cu₂O, Cs₂CO₃, DMSO at 110°), were applied to the synthesis of various N-(methoxypyridyl) pyrroles, indoles and benzimidazoles. The behavior of the different iodinated methoxypyridines was rationalized by evaluating the partial pos. charge on the carbon bearing iodine from the ¹H NMR chem. shift of the corresponding deiodinated substrates. The reaction was next connected with the deprotometalation-iodolysis step generating iodinated methoxypyridines: straight involvement of the crude iodo intermediates in pyrrole N-arylation afforded the expected N-(methoxypyridyl) pyrroles in good yields. Several synthesized N-(methoxypyridyl) azoles exerted low to moderate antiproliferative activity in A2058 melanoma cells.

A coupling between various alkynylstannanes with α-iodo esters catalyzed by GaBr₃ under UV irradiation conditions has been described. A catalytic amount of GaBr₃ was essential, and a radical coupling with the generated alkynylgallium species was involved. The desired α-alkynyl esters were selectively obtained even in the presence of an aryl-I bond, which is a reactive site in a conventional palladium-catalyzed system.
