The trifluoromethylthio group (SCF3) is a fluorine chemotype that has experienced a strong acceleration of in- terest in the recent years. It is particularly true of the construction of new fluorinated architectures by electrophilic trifluoromethylthiolation. The spread of knowledge was already very active in this research domain in the sixties; however, gaseous and highly toxic trifluoromethanesulfenyl chloride (CF3SC1) was the only reagent available at that time. Nowadays, one really can speak of a revival in the field thanks to the rapid development of a wide pano- ply of reagents that are stable and easy to handle. This review provides a historical perspective of the development of shelf-stable electrophilic trifluoromethylthiolation reagents. 展开更多

Since the sulfur(Ⅵ)fluoride exchange reaction(SuFEx)was introduced by Sharpless and co-workers in 2014,this new-generation click chemistry has emerged as an efficient and reliable tool for creating modular intermolecular connections.Sulfonyl fluorides,one of the most important sulfur(Ⅵ)fluoride species,have attracted enormous attention in diverse fields,ranging from organic synthesis and material science,to chemical biology and drug discovery.This review aims to introduce seminal and recent progresses on the synthetic methods of sulfonyl fluorides,which include aromatic,aliphatic,alkenyl,and alkynyl sulfonyl fluorides.While not meant to be exhaustive,the purpose is to give a timely overview and insight in this field,and stimulate the development of more efficient synthetic methods of sulfonyl fluorides. 展开更多

The intramolecular cyclization of 2-alkynylanilines mediated by DMSO/SOCI_(2) was found to afford biologically interesting 3-methylthioindoles,which are rarely obtained by the exiting methods.DMSO could also be replaced with its deuterated counterpart,enabling the method applicable to the construction of indole skeleton bearing a SCD_(3) moiety at its 3-position. 展开更多
