Base‐Mediated Generation of Ketenimines from Ynamides: Addition of Hydrazones to Give Acetimidohydrazides**
Résumé
Under basic conditions, N-arylketenimines were generated in situ from N-Boc ynamides and reacted with various hydrazones. Under heating, an addition of the deprotonated hydrazone onto the central carbon of the ketenimines takes place giving rise to various acetimidohydrazides.
