Abstract

PURPOSE: To obtain the title compound usable as main constituents of chelating agents, detergents, etc. according to a novel method in high yield with ease, by reacting a dialkyl phosphite with an alkyl orthoformate and a specific amine, and by hydrolyzing the reaction product.
CONSTITUTION: A dialkyl phosphite of formula I: (R' is lower alkyl group) is reacted with an alkyl orthoformate of formula II: (R is R1) and an organic primary or secondary amine having a boiling point higher than that of a lower alcohol of the formula R-OH under heating to form an amino methylene-diphosphonate of formula III, which is then hydrolyzed to give the objective compound of formula IV, e.g. N- (p-tolyl)-aminomethylene-diphosphonic acid. A high-boiling monoalkylamine, dialkenylamine, dialkylamine, or piperidine may be cited as the specific amine.
USE: Active ingredients of herbicides.
