This disclosure relates to thio derivatives of N-trifluoroacetyl-N-phosphonomethylglycine esters, to herbicidal compositions containing same and to the herbicidal use thereof. The thio derivatives of N-trifluoroacetyl-N-phosphonomethylglycine esters are useful as herbicides.
The novel N-trifluoroacetyl-N-phosphonomethyl-glycinate thio derivatives of this invention are those having the formula
wherein R is an alkyl group containing from 1 to 10 carbon atoms, a chloro lower alkyl group containing from 1 to 4 carbon atoms and 1 to 3 chlorine groups, a lower alkoxy lower alkyl group containing from 3 to 6 carbon atoms or an alkoxyalkoxyalkyl group containing from 5 to 9 carbon atoms and R' is a member of the group consisting of lower alkylthio. lower alkenylthio, benzylthio, phenylthio, or substituted phenylthio wherein the phenyl group contains 1 to 2 substituents selected from the group consisting of halo, lower alkyl and lower alkoxy.
