Fluorinations with sulfur tetrafluoride and HF. 2. Preparation of trifluoromethylated thiazoles and isothiazoles
Several new trifluoromethylated thiazoles and isothiazoles have been prepared using SF4 on precursor carboxylic acids.This chemistry demonstrates the usefulness and applicability of the sulfur tetrafluoride fluorination to the preparation of novel thiazoles and isothiazoles.
