Abstract

Abstract : A practical, catalyst- and additive-free method for the oxidative dual C–H sulfenylation of imidazoheterocycles with nucleophiles and elemental sulfur using DMSO as both the solvent and oxidant was developed. Abstract : Dual C–H sulfenylation was used to obtain 3-vulcanized imidazoheterocycles using odorless elemental sulfur under catalyst- and additive-free conditions. C–H activation of both imidazoheterocycles and arylamines/arenols/indoles was realized by a practical protocol in which DMSO served as both a solvent and an internal oxidant.
