Trimethylaluminum addition to N-monoalkyl or N-monoaryl hydrazones followed by aldehyde addition leads to the formation of N-alkylated hydrazones in a new formal Mannich-type process. Addition compounds were also obtained in moderate yields with ketones. The mechanism as well as possible intermediates involved in the reaction are discussed.
