Synthesis of novel dithiocarbamates and xanthates using dialkyl azodicarboxylates: S–N bond formation

A one?pot three?component route for the synthesis of a novel category of dithiocarbamates or xanthates is developed by a reaction of in-situ generated dithiocarbamic acids or xanthates with dialkyl azodicarboxylates under mild and catalyst-free conditions. The reaction is characterized by a wide scope, high efficiency and straightforward isolation protocol. The synthetic utility of the dithiocarbamates and xanthates was demonstrated on the preparation of symmetrical and unsymmetrical thioureas, isothiocyanates, and thiocarbamates.

Photoinduced electron transfer reaction of tetraazathiapentalenes with trialkylamines

The photoinduced electron transfer reaction of tetraazathiapentalenes with trialkylamines gives thiourea derivatives by dialkylamination of isothiocyanate derivatives, through radical anions of tetraazathiapentalenes and radical cations of trialkylamines.
