Herbicidal and/or plant-growth regulatory compositions comprising, together with a carrier and/or surface-active agent, an effective amount of at least one herbicidal and/or plant growth regulatory active agent selected from compounds of formula (1)
(in which
R represents an optionally substituted aralkyl group,
X represents an O-, N- or S-linked organic group, an optionally substituted hydrocarbyl group, a halogen atom, a hydroxy, amino, alkoxyamino, nitro, cyano, azido, sulpho or phospho group,
or together with the group R2e, X may represent a ketonic oxygen atom -O- or a group of formula -CH20-;
R1e represents a hydrogen atom or an optionally substituted hydrocarbyl group, or a formyl group;
R2e represents a hydrogen atom, a hydroxy group or an optionally substituted hydrocarbyl or O-linked hydrocarbyl group,
or, together with the group X, R2e may represent a ketonic oxygen atom -O- or a group of formula -CH20-;
R3a represents a hydrogen atom, a hydroxy group or an optionally substituted alkoxy, alkenyloxy, aralkoxy or C1-4 hydrocarbyl group;
R3e represents a hydrogen atom, a hydroxy group or an optionally substituted hydrocarbyl or O-linked hydrocarbyl group; and
R4e represents a hydrogen atom or an optionally substituted hydrocarbyl group)
and enantiomers and salts thereof.
Methods for preparing the compounds of formula (I) are described; the compositions are valuable as herbicides and/or plant-growth regulants, particularly for use with crops such as soya, rape, sugar-beet, cotton, wheat, maize and rice.
除草剂和/或植物生长调节剂组合物,包括与载体和/或表面活性剂一起的有效量的至少一种选自式(1)化合物的除草剂和/或植物生长调节活性剂
其中
R 代表任选取代的芳烷基、
X代表O-、N-或S-连接的有机基团、任选取代的烃基、卤素原子、羟基、氨基、烷氧基氨基、硝基、氰基、叠氮基、磺基或膦基、
或与基团 R2e 一起,X 可代表酮氧原子-O-或式-CH20-的基团;
R1e 代表氢原子或任选取代的烃基或甲酰基;
R2e 代表氢原子、羟基或任选取代的烃基或 O 键烃基、
或 R2e 与基团 X 一起代表酮氧原子-O-或式-CH20-的基团;
R3a 代表氢原子、羟基或任选取代的烷氧基、烯氧基、烷氧基或 C1-4 烃基;
R3e 代表氢原子、羟基或任选取代的烃基或 O 键烃基
R4e 代表氢原子或任选取代的烃基)
及其对映体和盐。
描述了制备式 (I) 化合物的方法;这些组合物可用作除草剂和/或植物生长调节剂,尤其适用于大豆、油菜、甜菜、棉花、小麦、玉米和水稻等作物。
