标题：Transition-Metal-Free Conversion of Trifluoropropanamides into Cyanoformamides through C−CF3 Bond Cleavage and Nitrogenation
Abstact：A new transition-metal-free transformation of trifluoropropanamides into cyanoformamides through a sequence of C−CF3 bond cleavage and nitrogenation using tert-butyl nitrite as the nitrogen source is described. The method features direct detrifluoromethylation, broad substrate scopes, and excellent selectivity control, representing a new shortcut for constructing the nitrile group involving C−CF3 σ- bond cleavage.
