Abstract (en)

[origin: WO9110658A1] Compounds of formula (2) and isomeric and/or tautomeric forms thereof: wherein A is a C1-C4 alkylene or C3-C4 alkenylene group optionally substituted with 1-4 C1-C3 alkyl substituents; X is O, S, SO, SO2, NR<10> or a single bond; R<1> is H, or one of a number of specified groups, or M; R<2> is C1-C6 alkyl, or one of a number of other specified groups; R<3> and R<4> are independently H or C1-C4 alkyl; R<5> and R<6> are independently C1-C4 alkyl or one of a number of other specified groups; or, R<5> and R<6> together with the carbon atom to which they are attached form one of a number of specified carbocyclic or heterocyclic rings which may be substituted with specified substituents; R<7>, R<8> and R<9> are independently H or one of a number of specified groups; R<10> is H or one of a number of specified groups; and M is Li<+>, Na<+>, K<+>, NH4<+>, or N(R<11>)4<+> where R<11> is C1-C4 alkyl, processes for preparing them, herbicidal and plant growth regulating compositions containing them and methods for regulating the growth of a plant and selectively inhibiting, damaging or killing weed grasses in a broad-leaf crop involving them.
