• Reacts with aldehydes to form benzoylhydrazones. These have been reported as useful, stable surrogates of unstable imines in allylation, Mannich-type and cyanide addition reactions: J. Org. Chem., 64, 8054 (1999).
• Hydrazides can be reduced to aldehydes with NaBH4 in the presence of CuCl2. For benzhydrazide, an 82% yield was reported: Org. Prep. Proced. Int., 20, 405 (1988).
