Synthesis of Hypervalent Iodine Diazo Compounds and Their Application in Organic Synthesis

Chemistry - A European Journal, Journal Year: 2023, Volume and Issue: 30(5)

Published: Oct. 17, 2023

Diazomethyl-substituted iodine(III) compounds with electron-withdrawing groups (EWG) connected to diazo methyl center were a type of donor-acceptor potential reaction abilities similar ordinary compounds. Although several diazomethyl-substituted synthesized and used in the nucleophilic substitution reactions as early 1994, synthesis application new have only been reported certain extent recent years. In presence rhodium catalyst, photocatalyst, or nucleophiles, can be converted into rhodium-carbenes, diazomethyl radicals, ester radicals intermediates, which key intermediates for formation chemical bonds. The aim this review is give an overview organic synthesis.

Chemistry of gem-Difluorovinyl Sulfonates

Mini-Reviews in Organic Chemistry, Journal Year: 2022, Volume and Issue: 20(8), P. 842 - 853

Published: Sept. 30, 2022

Abstract: Among various emerging organofluorine molecules, gem-difluorovinyl sulfonates are attractive building blocks and less used in organic reactions. This review article is concerned with recent advances reactions using years. We discussed the of aldehydes, amines, imines, amides, boronic acids, aryl halides, etc. or addition, reduction, substitution intramolecular 1,3-sulfonyl migration gemdifluorovinyl nine approaches. The synthetic strategies described this provided diversely substituted fluorinated molecules.
