  Two unprecedented and complementary synthetic strategies for S- and C-difluoromethylation of 2-substituted benzothiazoles have been developed by taking advantage of the remarkably different reactivity of CF2H– and 2-PySO2CF2– nucleophiles. A variety of structurally diverse difluoromethyl 2-isocyanophenyl sulfides and 2-difluoromethylated benzothiazoles were synthesized with these two new synthetic
