Described herein is a simple, novel, one-pot acylamination reaction of unactivated alcohols. This reaction employs the combination of PCl3 and triflic anhydride (Tf2O) or copper triflate Cu(OTf)2, which serves as a source of P(IV)-activated complex for nitriles to react under the Ritter-type mechanism. The synthetic utility of Tf2O-promoted reactions was demonstrated by its effectiveness to generate different
