WebWe reported here a radical hydrotrifluoromethylation of ynamides to provide an alternative route to β-CF3 enamines. By the use of PhICF3Cl as the CF3 reagent and DMF as the H-donor, the reaction smoothly occurred in the presence of NaH at room temperature. Further reduction of resulting β-CF3 enamines efficiently delivered β-CF3 amines.
