Pendem, Venkata Bhavanarushi published the artcileIron-promoted sulfur sequestration for the substituent-dependent regioselective synthesis of tetrazoles and guanidines, SDS of cas: 3696-23-9, the publication is Journal of Sulfur Chemistry (2021), 42(5), 499-509, database is CAplus.

Herein, a facile and versatile synthetic methodol. for the construction of tetrazoles and guanidines in the presence of an eco-friendly, inexpensive and easily available iron reagent were established. Aromatic thioureas with electron-donating substituents produced their resp. target products in quant. yield. In contrast, when electron-withdrawing substituted aromatic thioureas were used, the expected products were obtained in reduced yield. However, the desired products were obtained in good yield at moderate temperature In addition, mechanistic studies revealed that the synthetic route involved iron-based subsequent reactions of addition and removal of sulfur.

Hu, Penghui published the artcileBio-inspired iron-catalyzed oxidation of alkylarenes enables late-stage oxidation of complex methylarenes to arylaldehydes, Quality Control of 209919-30-2, the publication is Nature Communications (2019), 10(1), 1-9, database is CAplus and MEDLINE.

A bio-inspired iron-catalyzed polymethylhydrosiloxane-promoted aerobic oxidation of methylarenes to arylaldehydes with high yields and selectivities was reported. Notably, this method can tolerate oxidation-labile and reactive boronic acid group, which is normally required to be transformed immediately after its introduction and represents a significant advance in the area of the chem. of organoboronic acids, including the ability to incorporate both aldehyde and ketone functionalities into unprotected arylboronic acids, a class that can be difficult to access by current means. The robustness of this protocol was demonstrated on the late-stage oxidation of complex bioactive mols., including dehydroabietic acid, Gemfibrozil, Tocopherol nicotinate, a complex polyol structure and structurally complex arylboronic acids.

Pasha, Maira published the artcileOrganocatalytic diastereo- and enantioselective oxa-hetero-Diels-Alder reactions of enones with aryl trifluoromethyl ketones for the synthesis of trifluoromethyl-substituted tetrahydropyrans, Quality Control of 21286-54-4, the publication is Organic & Biomolecular Chemistry (2021), 19(42), 9242-9250, database is CAplus and MEDLINE.

Here diastereo- and enantioselective oxa-hetero-Diels-Alder reactions catalyzed by amine-based catalyst systems that afford trifluoromethyl-substituted tetrahydropyranones was reported. Catalyst systems and conditions suitable for the reactions to provide the desired diastereomer products with high enantioselectivities were identified, and various trifluoromethyl-substituted tetrahydropyranones were synthesized with high diastereo- and enantioselectivities. Mechanistic investigation suggested that the reactions involve a [4 + 2] cycloaddition pathway, in which the enamine of the enone acts as the diene and the ketone carbonyl group of the aryl trifluoromethyl ketone acts as the dienophile. In this study, tetrahydropyran derivatives with the desired stereochem. that are difficult to synthesize by previously reported methods were concisely obtained, and the range of tetrahydropyran derivatives that can be synthesized was expanded.

Synthesis of the monomers was improved by using the “sequential drop”. By this way, the yield of the monomers was increased, and drain of the materials was decreased as compared with “fully mixing”. Using Wurtz-type coupling of methylphenethyldichlorosilane and trichloromethylsilane branched polysilanes: P(MPES-to-MS) were synthesized by “pre-polymerization” and “mixing polymerization”.

Bhattacherjee, Debojit published the artcileTrisulfides over disulfides: highly selective synthetic strategies, anti-proliferative activities and sustained H₂S release profiles, Product Details of C7H6Cl2, the publication is Chemical Communications (Cambridge, United Kingdom) (2019), 55(90), 13534-13537, database is CAplus and MEDLINE.

Temperature- and solvent-induced selective synthesis of trisulfides and disulfides is demonstrated. A remarkable selectivity was achieved using Na₂S as a sulfur-transfer agent under mild, greener, catalyst-free and additive-free conditions. This study reveals trisulfides as a better model than disulfides in general for a sustained release of H₂S and potent anti-cancer activities.

The oxidation of p-methoxy benzyl (PMB) ethers e.g., 1-methoxy-4-[(3-phenylpropoxy)methyl]benzene was achieved using nitroxyl radical catalyst I, which contains electron-withdrawing ester groups adjacent to the nitroxyl group. The oxidative deprotection of the PMB moieties on the hydroxy groups was observed upon treatment of I with 1 equiv of the co-oxidant Ph iodonium bis(trifluoroacetate) (PIFA). The corresponding carbonyl compounds e.g., 3-phenylpropanal were obtained by treating the PMB-protected alcs., e.g., 3-phenylpropan-1-ol, with I and an excess of PIFA.

Murase, Hiroaki published the artcileSynthesis of polysilanes using Mg and Lewis acid and the consideration of this reaction mechanism, Application of Dichloro(hexyl)(methyl)silane, the publication is Materials Sciences and Applications (2015), 6(6), 576-590, database is CAplus.

Reduction of dichlorosilanes with Mg metal in the presence of LiCl and Lewis acid such as FeCl₂ or ZnCl₂ was found to be the highly practical method for the synthesis of polysilanes (PS). This method is so useful and practical that PS can be prepared by stirring dichlorosilanes at room temperature This method was successfully applied for the synthesis of various types of PS having a linear structure, a cyclic structure and silane-styrene copolymers as another type of PS. The structure of the reaction intermediates was also analyzed. At the initiation stage the results of FD-MS (Field desorption mass spectrometry) and GPC (Gel permeation chromatog.) showed that linear oligomers were mainly formed by stepwise reactions, and then the high polymers and cyclic oligomers were formed in parallel.
