## Abstract 3‐Phenylimidazo[1,5‐__a__]pyridinium salts are easily prepared in excellent yield by thermolysis of phenylchlorodiazirine in the presence of 2‐pyridyl Schiff bases (2‐Pyr‐CH=NR, where R is an aromatic or alkyl group). When the reaction is conducted in an alkane solvent, the salts precip
