Abstract

Procedure for the manufacture of N-phosphonomethylglycine and its intermediates, characterized in that a) A compound of formula I is hydrolyzed: **(See formula)** wherein R is hydrogen or a low alkyl group, with an aqueous hydrazic acid of a halogen; or b) Bis-N, N- (chloromethyl) -diquetopiperazine is transformed into a trialphosphite of formula II: **(See formula)** (where R1 is a low alkyl group) and the compound obtained from formula I, where R is a low alkyl group, is hydrolyzed with an aqueous hydrazic acid of a halogen; or c) the disodium salt of diketopiperazine is transformed into chloromethylphosphoric acid and the obtained compound of formula I, in which R is hydrogen, is hydrolyzed with an aqueous hydrazic acid of a halogen.
