O-aryl N-phosphonomethylglycinonitriles having utility as herbicides are prepared by reacting in the absence of acidic catalysts 1,3,5-tricyanomethyl-hexahydro-1,3,5-triazine with a diaryl phosphite. The products can be hydrolyzed to form N-phosphonomethylglycine.
N,N'-methylenebis-[(O,O-diaryl N-phosphonomethylglycinonitriles] are described as well as a process for producing same. These compounds are useful as herbicides.
