[reaction: see text] A mild, practical, one-pot method for the generation of imidoyl chlorides and their subsequent in situ reaction with pyridine-1-oxides is described. The imidoyl chlorides were formed from the reaction of secondary amides with a stoichiometric amount of oxalylchloride and 2,6-lutidine in CH(2)Cl(2) at 0 degrees C. Upon warming of the reaction mixture to room temperature in the
