Compounds of the formula (2), including all isomeric and/ or tautomeric forms.
where X is 0 or NR6, R' is an organic group, hydrogen or an inorganic cation, R2 to R6 are independently organic groups or hydrogen are disclosed. The presence of the group R5 gives improved herbicidal properties.
R5 is selected from the group consisting of: allyl; substituted alkyl wherein the alkyl group is substituted with a substituent selected from the group consisting of alkoxy, alkylthio, optionally substituted phenyl, and optionally substituted heterocycle; or
COXR4 and R5 together with the carbon to which they are attached form a substituted or unsubstituted 5- or 6- membered heterocyclic ring. The spirocyclic compounds are preferred. The synthesis of the compounds, and herbicidal (including plant growth regulating) uses and compositions, are disclosed.
式(2)化合物,包括所有异构体和/或同分异构体形式。
其中 X 为 0 或 NR6,R'为有机基团、氢或无机阳离子,R2 至 R6 独立地为有机基团或氢。基团 R5 的存在提高了除草性能。
R5 选自以下组:烯丙基;取代的烷基,其中烷基被选自以下组的取代基取代:烷氧基、烷硫基、任选取代的苯基和任选取代的杂环;或
COXR4 和 R5 与它们所连接的碳一起形成一个取代或未取代的 5 或 6 位杂环。优选螺环化合物。公开了这些化合物的合成以及除草(包括植物生长调节)用途和组合物。
