H. Yamanaka et al., A NEW PRACTICAL AND CONVENIENT ACCESS TO THE SYNTHESIS OF N,N-DIALKYL-3,3,3-TRIFLUOROPROPANAMIDES, Chemistry Letters, (7), 1998, pp. 615-616
N,N-Dialkyl-3,3,3-trifluoropropanamides were readily synthesized in go
od to excellent yields through N,N-dialkyl(3,3,3-trifluoro-1-propynyl)
amines, which were generated by the reaction of N,N-dialkyl(2,2,3,3,3-
pentafluoropropyl)- or -(2,3,3,3tetrafluoro-1-propenyl)amines with lit
hium diisopropylamide in the presence or absence of N,N'-dimethylpropy
leneurea at room temperature or 0 degrees C.
