This disclosure relates to derivatives of N-trifluoroacetyl-N-phosphonomethylglycinates wherein different moieties are attached to the phosphorus atom, to herbicidal compositions containing same and to the herbicidal use thereof.
The novel N-trifluoroacetyl-N- phosphonomethylglycinates of this invention are those having the formula
wherein R is an alkyl group of from 1 to 10 carbon atoms or chlorinated lower alkyl group, R, is a member of the group consisting of lower alkoxy, lower alkylthio, phenoxy, phenylthio, substituted phenoxy, substituted phenylthio, lower alkylamino, lower dialkylamino, morpholino and N-piperidinoamino and R2 is a member of the group consisting of lower alkylthio, phenoxy, phenylthio, substituted phenoxy, substituted phenylthio, lower alkylamino, lower dialkylamino, lower alkenylamino, lower dialkenylamino, lower alkynylamino, lower dialkynylamino, morpholino and N-piperidinoamino with the proviso that R, and R2 cannot represent the same group.
本发明涉及N-三氟乙酰基-N-膦酰甲基甘氨酸盐的衍生物(其中磷原子上连接有不同的分子)、含有这些衍生物的除草组合物及其除草用途。
