Oxidative Dimerization of Sulfenyl Chlorides into Thiosulfonates under the Action of Hexamethylphosphoramide

摘要

Compounds containing electrophilie sulfur 'S(II) are mainly known as important reagents in alkene chemistry. Different aspects of reactions of sulfenyl chlorides, sulfur dichloride, and other S(II) reagents with a wide range of unsaturated compounds, including linear and cyclic alkenes, alkynes, etc., are described in the literature [1, 2]. However, in spite of the considerable synthetic and theoretical value of these reagents related in alkene chemistry to weak electrophiles [1,3], their reactions with n-donor substrates have not been studied. There are few reports in the literature on the reaction of this group of electrophiles with typical n-donor compounds [4, 5].
