CA 1340284

A compound of formula (I): (see fig. I) or a salt, enamine, acylate, sulphonate carbamate or ether derivative thereof; wherein X, X1 and X2 are independently oxygen or sulphur, R1 is an optionally substituted heterocyclic or cycloalkyl group, and Y is an optionally substituted C2-C4 alkylene group which is optionally interposed by an oxygen atom, a group (see fig. II) a group (see fig. III) or an optionally mono-substituted nitrogen atom, wherein p is 0, 1 or 2, s is 0 or 1 and R b is alkyl or alkoxy; provided that when X, X1 and X2 are oxygen, R1 is not pyridyl or pyrimidinyl. Processes for the preparation of these compounds and herbicidal compositions containing them are also described and claimed.
