Convenient methods for the synthesis of functionalized organophosphorus compounds containing carbonyl groups as well as di- or trialkoxymethyl fragments attached to phosphorus, and their derivatives, starting from the available derivatives of trivalent phosphorus acids, are proposed, and some properties of the new functionalized organophosphorus compounds are presented. So, the alkylation and acylation

aminomethylation of the several esters of hypophosphorous acid using chloro-, alkoxy-, and amino-substituted methylamines of various structure is proposed as convenient method for the synthesis of newfunctionalizedaminomethylphosphonites and bis(aminomethyl)phosphinates. Also O,O-diethyl(pivaloyl)phosphonite is successfully applied in the aminomethylation as a synthetic analog of unstable diethoxyphosphine.
