N-dimethylaluminum-N′,N′-dimethylhydrazide, synthesized from N,N-dimethylhydrazine and trimethylaluminum, reacts with aromatic ketones or with electronically unfavourable substrates to give the corresponding hydrazones in high yield. Subsequent exchange with anhydrous hydrazine affords the N-unsubstituted hydrazones.
