Abstract
Abstract The reaction of N -fluoropyridinium triflate with isonitriles in acetonitrile and propionitrile in the presence of NaBH(OAc) 3 led to the formation of the corresponding imidazo[1,2- a ]pyridines in 44–73% yields. The proposed reaction mechanism involves the intermediate formation of a highly reactive carbene species and apparent reduction of the pyridinium intermediate with NaBH(OAc) 3 to yield the targeted heterocycles.
