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
An iodine-mediated synthesis strategy for rapid synthesis of sulfenamides was reported. By using iodine as oxidant, various thiophenols and amines (mainly secondary amines) could quickly and smoothly proceed the CDC reaction, affording the target N−S formation products with good yields. The protocol features metal-free, easy performance, short reaction time, variety of substrates and good yields, showing
