A simple and efficient approach for synthesis of hydrazones from carbonyl compounds and hydrazides catalyzed by meglumine

A simple, environmentally benign protocol for synthesis of hydrazones from carbonyl compounds and hydrazides has been developed in the presence of meglumine in aqueous-ethanol media at room temperature. The salient features of the present protocol are mild reaction conditions, short reaction time, high yields, operational simplicity, metal-free, applicability toward large-scale synthesis as well as the use of biodegradable and inexpensive catalyst.
