Triazole and imidazole derivatives of the formula:
wherein R1 is H, optionally substituted alkenyl or alkynyl, or OSi (CH3)3;
R2 is alkyl, vinyl or optionally substituted phenyl;
R3 is alkyl, optionally substituted phenyl, hydroxy or alkoxy;
R4 is H or CH3;
A is CH or H;
and salts and metal complexes thereof, exhibit potent fungicidal activity. The compounds may be used to control fungus diseases of living plants, for which purpose they may be formulated into fungicidal compositions in conventional manner.
The novel compounds may be made e.g. by reacting an appropriate chloromethylsilane of formula:
with an alkali metal salt of 1,2,4-triazole or imidazole.
式中的三唑和咪唑衍生物:
其中 R1 为 H、任选取代的烯基或炔基或 OSi (CH3)3;
R2 是烷基、乙烯基或任选取代的苯基
R3 是烷基、任选取代的苯基、羟基或烷氧基;
R4 是 H 或 CH3;
A 是 CH 或 H;
及其盐类和金属配合物具有强效杀菌活性。这些化合物可用于防治活体植物的真菌疾病,为此可按常规方法将其配制成杀菌组合物。
新型化合物可通过将适当的式......氯甲基硅烷与式......1 的碱金属盐反应制成:
与 1,2,4-三唑或咪唑的碱金属盐反应。
