Methylenedioxy imidazolinyl acids of the general formula I:
wherein W represents CH or N;
n represents zero or 1 when W is N, and represents zero when W is CH;
one of X and Y represents a carbonyl group and the other represents the alkylidene group = CR4R5;
R, and R2, which may be the same or different, each independently represents a hydrogen atom or an optionally substituted alkyl or cycloalkyl group;
R3 represents a hydrogen atom or a salt-forming cation or an optionally halogenated alkyl, alkenyl, alkynyl, alkoxyalkyl, cycloalkyl, phenyl, furyl or benzyl group;
R4 represents an alkyl or cycloalkyl group; R5 represents an optionally substituted alkyl, cycloalkyl, alkenyl, phenyl, halophenyl or benzyl group, or R4, R5, and the interjacent carbon atom, together represent a cycloalkyl group; and Q represents a hydrogen atom or an acyl group. Also, processes for the preparation of such compounds, and their use as herbicides.
