摘要:
                                Trifluoromethylated thiobenzanilides are efficiently converted to 2-trifluoromethylbenzothiazoles via intramolecular oxidative cyclization under CAN/NaHCO(3) oxidation, while the dimerized products with "-S-S-" bond linkage are obtained when PIDA is used as an oxidant.
