A highly efficient and simple synthesis of dithiocarbamates is reported in the one-pot reaction of amines, CS₂, and alkyl halides without using a catalyst under solvent-free conditions. The mild reaction conditions, high yields, and broad scope of the reaction illustrate the good synthetic utility of this method. The reaction is a highly atom-economic process for production of dithiocarbamates and can be successfully used in large amount for the pharmaceutical or agrochemical industries.
