摘要：

The title reaction was achieved by UV (254 nm) irradiation with CF3I. The methylthio group was introduced to increase electron density and to limit available reactive sites in the rings. Following trifluoromethylation, the methylthio groups were readily removed by hydrogenolysis (Raney Ni) to give the desired trifluoromethyl heterocycles.
