摘要：

An efficient method for the synthesis of 1,2-benzisothiazoles from amidines and elemental sulfur via N-S/C-S bond formation under transition-metal-free conditions is described. This reaction is performed smoothly under simple conditions to give the corresponding products in good to high yields with good functional group tolerance.
