Multicomponent synthesis of dithiocarbamates starting from vinyl sulfones/sulfoxides and their use in polymerization reactions

Abstract

A catalyst- and solvent-free procedure for the synthesis of dithiocarbamates from amines, carbon disulfide (CS₂) and vinyl sulfones/sulfoxides is reported. This protocol provides a simple, high yielding and green approach for the synthesis of novel dithiocarbamates with commercially available starting materials. Also, three-component polyaddition of diamines, CS₂ and divinyl sulfone was successfully performed without the use of a catalyst to provide the corresponding polymers containing dithiocarbamate (dithiourethane) and sulfone moieties.
