Abstract
A simple, efficient, facile and surface mediated method for synthesis of hydrazides of organophosphorous acids has been developed from their corresponding chloridates using calcium oxides as a solid support at room temperature. The developed method gave the desired hydrazides in excellent yields (75-92%) and avoids the use of column chromatography.
