Abstract:
The synthesis of new derivatives 2 of α-hydrazino-(disubstituted)- alkylphosphonic acids by the Lewis acid mediated addition of dialkylphosphite to hydrazones, derived from benzoylhydrazine and aliphatic ketones, is described. Reactions were successfully and catalytically promoted by BF3 etherate under mild condition in methylene chloride at room temperature.
