A General and Straightforward Method for the Synthesis of 2-Trifluoromethylbenzothiazoles
摘要:
An efficient one-pot method for the synthesis of 2-trifluoromethylbenzothiazoles by the treatment of trifluoromethylimidoyl chlorides with sodium hydrosulfide hydrate using PdCl(2) as the sole catalyst in DMSO is described. The reaction proceeds via thiolation/C H bond functionalization/C S bond formation in moderate to high yields with good functional group tolerance.
