A novel single-step preparation of free-base and metalloporphyrazines from maleonitriles was accomplished for the first time by treatment with metal salts, hexamethyldisilazane (HMDS) and p-toluene sulfonic acid (PTSA) in DMF at 120 degrees C. This reaction provides a new preparative method under mild conditions for direct synthesis of metalloporphyrazines having a variety of metals and substituted maleonitriles.
