Abstract
A compound having the structural formula ##STR1## wherein: Y is selected from O and S; PA0 R.sub.1 and R.sub.4 are independently selected from fluorinated methyl, chlorofluorinated methyl, and C.sub.1 -C.sub.4 alkyl, provided that not both R.sub.1 and R.sub.4 may be C.sub.1 -C.sub.4 alkyl; PA0 R.sub.2 is selected from hydrogen, lower alkyl, haloalkyl, alkenyl, alkynyl, haloalkenyl, and a cation; PA0 R.sub.3 is selected from C.sub.1 -C.sub.5 alkyl, cycloalkyl, cycloalkylalkyl, hydroxy, and alkoxy; and PA0 X is selected from ##STR2## in which R.sub.8 is selected from H, alkyl and CF.sub.3 and R.sub.10 is selected from F, Cl, --OR.sup.1, --SR.sup.1, --NHR.sup.1, --N(R.sup.1).sub.2, phenyl, substituted phenyl, and --P(OR.sup.1).sub.2 PA0 where R.sup.1 is as defined above; ##STR3## wherein R.sup.1 is as defined above; ##STR4## wherein R.sub.14 and R.sub.15 are independently selected from hydrogen and alkyl; and --N.dbd.C.dbd.O and their use as herbicides.
