A copper-catalyzed isothiocyanation of amines with sodium bromodifluoroacetate and sulfur in the absence of organophosphine has been established. This approach represents a simple and efficient one-pot synthesis of isothiocyanates, and features excellent functional group tolerance and the use of a cheap, safe and odorless sulfur source. Moreover, this process could directly provide isothiocyanate analogous bioactive molecules, thiocarbonyl-containing pesticides and facile construction of benzoxazole and benzimidazole frames.

In the presence of AgBF4, the ammonolysis-cyclization tandem reactions of various 2-alkynylbenzenamines with tetraalkylthiuram disulfides afforded the corresponding 4-methylene-4H-benzo[d][1,3]thiazin-2-amines in moderate to good yields.
