w 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 sigma-bond cleavage.
