Abstract
The invention concerns novel compounds of the formula I and isomers thereof ##STR1## wherein: n is an integer selected from 2 to 4; PA1 m is zero or an integer selected from 1 to 3; PA1 X, which may be the same or different, are independently selected from halogen, alkyl, alkoxy and alkylthio; PA1 R.sup.1 is selected from hydrogen, 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 R.sup.4 is selected from hydrogen, halogen, alkyl, cyano and alkoxycarbonyl. The compounds of the invention show herbicidal properties and plant growth regulating properties and in further embodiments the invention provides processes for the preparation of compounds of formula I, intermediates useful in the preparation of the compounds of the formula I, compositions containing as active ingredient a compound of formula I, and herbicidal and plant growth regulating processes utilizing compounds of formula I.
