Abstract
Triesters of N-phosphonomethyl glycine were prepd. by subjecting a soln. of a tetraester of N-phosphonomethyliminodiacetic acid in organic solvent contg. a supporting electrolyte to a direct current at a current density of 0.01 to 100 ma/cm2. Thus tetraester was oxidized to the triester. The solvent should dissolve tetraester and the supporting electrolyte. This compd. was used to prepare herbicidal N-phosphonomethylglycine by hydrohysis with acid as dil. HCl.
