Abstract
The invention concerns novel compounds of the formula I ##STR1## wherein Z is selected from hydrogen, halogen, C.sub.1 to C.sub.6 alkyl, and C.sub.1 to C.sub.6 alkoxy; PA1 Y is selected from halogen, C.sub.1 to C.sub.6 alkyl and C.sub.1 to C.sub.6 alkoxy; PA1 X is selected from halogen, C.sub.1 to C.sub.6 alkyl and C.sub.1 to C.sub.6 alkoxy and if Y is methyl and Z is hydrogen or methyl then at least one of X is not methyl; PA1 R.sup.1 is selected from hydrogen, alkyl, alkenyl, alkynyl, substituted alkyl, alkylsulfonyl, arylsulfonyl, acyl and an inorganic or organic cation; PA1 R.sup.2 is selected from alkyl, substituted alkyl, alkenyl, haloalkenyl, alkynyl and haloalkynyl; PA1 R.sup.3 is selected from alkyl, fluoroalkyl, alkenyl, alkynyl and phenyl; and PA1 m is an integer chosen from 1 to 3. The compounds are cereal selective herbicides and in further embodiments the invention provides processes for the preparation of compounds of formula I, intermediates useful in the preparation of compounds of formula I, herbicidal compositions containing as active ingredient a compound of formula I, and processes for severely damaging or killing unwanted plants by applying to the plants or to…
