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.
具有除草剂用途的O-芳基N-磷酸甲基甘氨酸腈是通过在无酸性催化剂存在下将1,3,5-三氰基甲基-六氢-1,3,5-三嗪与二芳基磷酸酯反应制备的。这些产物可以水解形成N-磷酸甲基甘氨酸。
