ABSTRACT:
Alkyl-[di(benzyl) or di(aryl)]esters of N-phosphonomethyl glycine are produced by the reaction of a dibenzyl or diaryl phosphite with an N-methylene alkyl glycinate trimer. These esters and the hydrolysis products thereof containing at least one benzyloxy or aryloxy group bonded to phosphorus are novel compounds having the formula ##STR1## wherein R is a member of the group consisting of phenyl, benzyl, naphthyl, biphenylyl, benzyloxyphenyl and phenyl, benzyl or naphthyl groups substituted with from 1 to 3 groups selected from the class consisting of hydroxyl, lower alkyl, lower alkoxy, lower alkylthio, trifluoromethyl, carbo (lower alkoxy), nitro, or halo; R.sub.1 is hydrogen or an R group, and R.sub.2 is a lower alkyl group or hydrogen, and the strong acid salts of the compounds wherein neither R.sub.1 or R.sub.2 is H. These compounds are useful as post-emergent herbicides.
