In 2019,ACS Catalysis included an article by Peng, Jin-Bao; Wu, Fu-Peng; Li, Da; Geng, Hui-Qing; Qi, Xinxin; Ying, Jun; Wu, Xiao-Feng. Safety of 1-Iodo-2-methoxybenzene. The article was titled 《Palladium-Catalyzed Regioselective Carbonylative Coupling/Amination of Aryl Iodides with Unactivated Alkenes: Efficient Synthesis of β-Aminoketones》. The information in the text is summarized as follows:

The carbonylative coupling of aryl halides with unactivated alkenes remains a challenge, because of the low reactivity of acyl-palladium intermediate to the olefins. A palladium-catalyzed carbonylative coupling/amination of aryl iodides with unactivated alkenes for the synthesis of β-aminoketone derivatives was developed. With the assistance of a directing group (8-aminoquinoline, AQ), the coordination of the olefin to acyl-palladium complex can be enhanced, thereby promoting the acylpalladation across the C:C double bonds. A broad range of β-aminoketone derivatives were prepared in moderate to excellent yields with complete regioselectivity by using 4-pentenoic and 2-vinylbenzoic amide derivatives as the starting materials. This methodol. involves the formation of two C-C bonds as well as one C-N bond, and provided a method for the carbonylative difunctionalization of unactivated alkenes. In addition to this study using 1-Iodo-2-methoxybenzene, there are many other studies that have used 1-Iodo-2-methoxybenzene(cas: 529-28-2Safety of 1-Iodo-2-methoxybenzene) was used in this study.

In 2019,ACS Omega included an article by Grattan, Vincent; Vaino, Andrew R.; Prensky, Zachary; Hixon, Mark S.. Application of 4637-24-5. The article was titled 《Antipsychotic benzamides amisulpride and LB-102 display polypharmacy as racemates, S enantiomers engage receptors D2 and D3, while R enantiomers engage 5-HT7》. The information in the text is summarized as follows:

Benzamide antipsychotics such as amisulpride are dosed as racemates though efficacy is assumed to be mediated through S enantiomer binding to D2 receptors. At prescribed doses, the benzamides likely display polypharmacy since brain exposure should be sufficient to engage the 5-HT7 receptors, as well. Curiously, the studies herein reveal that racemic dosing is required to engage both targets since the D2 receptor has an almost 40-fold selectivity for the S enantiomer, while the 5-HT7 receptor has greater than 50-fold preference for the R enantiomer. The experimental part of the paper was very detailed, including the reaction process of N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5Application of 4637-24-5)

N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime. Reduction of nitro compounds, RNO2, by hydrogen or other reducing agents produces primary amines cleanly (i.e., without a mixture of products), but the method is mostly used for aromatic amines because of the limited availability of aliphatic nitro compounds. Reduction of nitriles and oximes (R2C=NOH) also yields primary amines.Application of 4637-24-5

In 2019,ChemPhysChem included an article by Demaison, Jean; Vogt, Natalja; Saragi, Rizalina Tama; Juanes, Marcos; Rudolph, Heinz Dieter; Lesarri, Alberto. Quality Control of 1,2-Diphenyldisulfane. The article was titled 《The S-S Bridge: A Mixed Experimental-Computational Estimation of the Equilibrium Structure of Diphenyl Disulfide》. The information in the text is summarized as follows:

The disulfide bridge (-S-S-) is an important structural motif in organic and protein chem., but only a few accurate equilibrium structures are documented. We report the results of supersonic-jet microwave spectroscopy experiments on the rotational spectra of di-Ph disulfide, C6H5-S-S-C6H5 (including all 13C and 34S monosubstituted isotopologues), and the determination of the equilibrium structure by the mixed estimation (ME) method. A single conformation of C2 symmetry was observed in the gas phase. This disulfide is a challenging target since its structure is determined by 34 independent parameters. Addnl., ab initio calculations revealed the presence of three low-frequency vibrations (<50 cm-1) associated to Ph torsions which would prevent the calculation of an accurate force field. For this reason, instead of the semiexperimental method, we used the mass-dependent (rm) method to fit the structural parameters concurrently to moments of inertia and predicate parameters, affected with appropriate uncertainties. The predicates were obtained by high-level quantum-chem. computations. A careful anal. of the results of different fits and a comparison with the ab initio optimizations confirms the validity of the used methods, providing detailed structural information on the title compound and the disulfide bridge. In the experimental materials used by the author, we found 1,2-Diphenyldisulfane(cas: 882-33-7Quality Control of 1,2-Diphenyldisulfane)

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation.
