An efficient and unprecedented green protocol has been developed for the synthesis of N,S-heterocycles fromstyrenes and alkyl dithiocarbamates with high to excellent yields. The reaction of primary or secondary amines, CS2, and styrenes was carried out in water in the presence of a catalytic amount of an inorganic base. All products were made by using an N-bromosuccinimide–H2O combination as a green
The synthesis of α-dithiocarbamato-alkyl-β-naphthols is reported via the Betti reaction of naphthols, aldehydes and ammonia-based dithiocarbamates in the presence of ZnCl2 undersolvent-freeconditions. High to excellent yields and simple reaction conditions are the main advantages of this reaction.
