Additions to alkenes via metal ion-promoted oxidation of 2,2′-dipyridyl disulphide and bis-(2-aminophenyl) disulphide
Abstract
Vicinal trifluoroacetoxysulphides, which readily afford vicinal hydroxysulphides, are obtained by oxidative addition of 2,2′-dipyridyl disulphide and of bis-(2-aminophenyl) disulphide to alkenes in dichloromethane–trifluoroacetic acid promoted by copper(II) acetate.
