The article was titled 《Palladium-Catalyzed Hiyama Cross-Couplings of Arylsilanes with 3-Iodoazetidine: Synthesis of 3-Arylazetidines》. The information in the text is summarized as follows:

The first palladium-catalyzed Hiyama cross-coupling reactions of arylsilanes with 3-iodoazetidine were described. The protocol provides a convenient access to a variety of useful 3-arylazetidines which are of great interest in pharmaceutical laboratories in moderate to good yields (30%-88%). In addition, this strategy has the advantage of easy operation and mild reaction conditions. In the experiment, the researchers used many compounds, for example, tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3Application of 301673-14-3)

tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3) is one of organic iodides. Organic iodides are used in veterinary products (Organic Iodide Powder) as a nutritional source of iodine. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs.

In 2019,Chemistry – A European Journal included an article by Hornum, Mick; Stendevad, Julie; Sharma, Pawan K.; Kumar, Pawan; Nielsen, Rasmus B.; Petersen, Michael; Nielsen, Poul. Safety of Trimethylsulfoxonium iodide. The article was titled 《Base-Pairing Properties of Double-Headed Nucleotides》. The information in the text is summarized as follows:

Nucleotides that contain two nucleobases (double-headed nucleotides) have the potential to condense the information of two sep. nucleotides into one. This presupposes that both bases must successfully pair with a cognate strand. Here, double-headed nucleotides that feature cytosine, guanine, thymine, adenine, hypoxanthine, and diaminopurine linked to the C2′-position of an arabinose scaffold were developed and examined in full detail. These monomeric units were efficiently prepared by convergent synthesis and incorporated into DNA oligonucleotides by means of the automated phosphoramidite method. Their pairing efficiency was assessed by UV-based melting-temperature anal. in several contexts and extensive mol. dynamics studies. Altogether, the results show that these double-headed nucleotides have a well-defined structure and invariably behave as functional dinucleotide mimics in DNA duplexes. In the experimental materials used by the author, we found Trimethylsulfoxonium iodide(cas: 1774-47-6Safety of Trimethylsulfoxonium iodide)

Trimethylsulfoxonium iodide(cas: 1774-47-6) reacts with sodium hydride to prepare dimethyloxosulfonium methylide, which is used as a methylene-transfer reagent in synthetic chemistry.

And the article was published in Journal of Organic Chemistry in 2019. COA of Formula: C5H4IN The author mentioned the following in the article:

Meso-Substituted calix[4]pyrroles 2-6 containing a direct meso-ethynyl linker displayed high binding affinities and unique conformational features on halide anion binding. A general conformational bias for the equatorial alignments of the meso-(aryl)ethynyl groups was observed in the host-halide complexes which was attributed to the repulsive anion-alkyne interactions and released steric strain. Such conformational features of host-halide complexes persisted even in the case of calix[4]pyrrole 6 bearing cationic meso components, which displayed the highest binding affinity for chloride anions among known meso-aryl calix[4]pyrroles. Synthetic details, conformational features, and comparative halide anion binding properties of this series of calix[4]pyrroles are described. In the part of experimental materials, we found many familiar compounds, such as 4-Iodopyridine(cas: 15854-87-2COA of Formula: C5H4IN)

An efficient method for the synthesis of alkyl indium reagents by an indium(III) or lead(II) halide-catalyzed direct insertion of indium into alkyl iodides and their applications in palladium-catalyzed cross-coupling reactions with aryl halides is developed. NMR and ESI-MS analyses indicated that rather than the formation of the commonly recognized alkyl indium sesquihalide with the formulation of R3In2X3, the formed alkyl indium reagent in the present protocol should be a mixture of an alkyl indium dihalide (RInX2) and a dialkyl indium halide (R2InX) (both of them presumably exist as dimers). The results came from multiple reactions, including the reaction of 4-Iodobenzaldehyde(cas: 15164-44-0Name: 4-Iodobenzaldehyde)

And the article was published in ACS Applied Materials & Interfaces in 2019. Formula: C6H4BrI The author mentioned the following in the article:

A novel, efficient, deep-blue fluorescent emitter mPAC, with a meta-connected donor-acceptor structure containing phenanthroimidazole (PPI) as the donor and phenylcarbazole-substituted anthracene (An-CzP) as the acceptor, was designed and synthesized. The meta-linkage provided a highly twisted mol. conformation, which efficiently interrupts the intramol. π-conjugation, resulting in a deep-blue emission. The optimized nondoped device based on mPAC displayed a deep-blue emission with a narrow full width at half-maximum of 56 nm and Commission Internationale de L’Eclairage coordinates of (0.16, 0.09). The maximum external quantum efficiency (EQEmax) is 6.76%, corresponding to a high exciton utilization efficiency (EUE) of 59.3-88.9%. Exptl. results and theor. anal. indicated that the high EUE is mainly ascribed to the reverse intersystem crossing (RISC) from T2 to S1, a “”hot exciton”” path in which the large T2-T1 energy gap (1.45 eV) and small T2-S1 energy difference (0.18 eV, T2 > S1) hamper the internal crossing from T2 to T1 and facilitate the RISC process. For the hot exciton path, the T2 state can be feasibly arranged to a high energy level, forming a thermal equilibrium with S1, even slightly higher than the deep-blue S1 to realize an exergonic RISC process, which is usually difficult for the thermally activated delayed fluorescence emitters.

The article was titled 《Ru-Tethered (R,R)-TsDPEN with DMAB as an efficient catalytic system for high enantioselective one-pot synthesis of chiral β-aminol via asymmetric transfer hydrogenation》.Electric Literature of C6H5ClIN The article contains the following contents:

This work reflected Ru-tethered-TsDPEN as an active chiral catalyst for one pot selective synthesis of optically active α-substituted alcs. ArCH(OH)CH2NHAr1 [Ar = Ph, 2-FC6H4, 2,3-(MeO)2C6H3, etc.; Ar1 = Ph, 4-MeC6H4, 4-ClC6H4, 4-Cl-2-I-C6H3, etc.; stereo = S] and its derivatives from α-bromo ketones ArCOCH2Br in presence of dimethylamine borane (DMAB) as hydrogen source. Various Ru-chiral catalysts were screened and methodol. proceeded via a (R,R) Ru-tethered TsDPEN catalyst through asym. transfer hydrogenation (ATH) of in-situ formed ketones to corresponding chiral β-aminol product. Thus, Ru-tethered TsDPEN-DMAB catalytic system works efficiently with higher yield and high enantiomeric excess over others for ATH process. Based on a study of ortho, meta and para substituted α-bromo acetophenone derivatives, effective enantioselectivity was observed for ortho substituted β-aminol.

Yang, Zhen; Koenigs, Rene M. published their research in Chemistry – A European Journal in 2021. The article was titled 《Photoinduced Palladium-Catalyzed Dicarbofunctionalization of Terminal Alkynes》.Application In Synthesis of tert-Butyl 4-iodopiperidine-1-carboxylate The article contains the following contents:

Herein, a conceptually distinct approach was developed that allowed for the dicarbofunctionalization of alkynes at room temperature using simple, bench-stable alkyl iodides and a second mol. of alkyne as coupling partner. Specifically, the photochem. activation of palladium complexes enabled this strategic dicarbofunctionalization via addition of alkyl radicals from secondary and tertiary alkyl iodides and formation of an intermediate palladium vinyl complex that could undergo subsequent Sonogashira reaction with a second alkyne mol. This alkylation-alkynylation sequence allowed the one-step synthesis of 1,3-enynes including heteroarenes and biol. active compounds with high efficiency without exogenous photosensitizers or oxidants and now opens up pathways towards cascade reactions via photochem. palladium catalysis. In the experiment, the researchers used many compounds, for example, tert-Butyl 4-iodopiperidine-1-carboxylate(cas: 301673-14-3Application In Synthesis of tert-Butyl 4-iodopiperidine-1-carboxylate)
