The invention provides fungicidal compositions containing benzyl-tris(aryl)- phosphonium salts of the general formula
in which R¹ represents an optionally substituted alkyl or alkoxy group; R² represents a hydrogen atom or an optionally substituted alkyl group; R³, R⁴ and R⁵ independently represent a hydrogen or halogen atom or an optionally substituted alkyl or alkoxy group; and A⁻ represents an anion processes for the preparation of such compounds. Certain of the compounds of formula I are novel and the invention therefore also provides processes for the preparation of such compounds and their use as fungicides.
本发明提供了含有通式如下的苄基-三(芳基)-鏻盐的杀菌组合物
其中R¹代表任选取代的烷基或烷氧基;R²代表氢原子或任选取代的烷基;R³、R⁴和R⁵各自代表氢原子、卤素原子或任选取代的烷基或烷氧基;以及A-代表阴离子 制备此类化合物的工艺。式 I 的某些化合物是新颖的,因此本发明还提供了制备此类化合物及其用作杀真菌剂的工艺。
