Novel thiadiazole compounds are disclosed which contain in the 5 position, C-linked moieties which are either acyclic hydrocarbon radicals or halogenated acyclic hydrocarbon radicals (in which case each halogen is independently selected from F, Cl and Br). These novel compounds also contain an exocyclic nitrogen in the 2 position, and some of them contain the exocyclic substituent: ##STR1## wherein R.sub.3 is a lower acyclic hydrocarbon radical and R.sub.4 is either H or a lower acyclic hydrocarbon radical. Synthesis of these compounds is disclosed, including synthesis of those which exhibit isomerism and/or tautomerism. Various of these compounds have various agricultural utilities (e.g. as herbicides, insecticides, acaricides and fungicides), each of them having at least one such biological utility. Methods of using these compounds in phytotoxic fungicidal, acaricidal and insecticidal applications are disclosed.
本发明揭示了一类新型噻二唑化合物,其中在5位位置含有C-链连接基团,该基团可以是无环烃基或卤代无环烃基团(在这种情况下,每个卤素独立选择自F、Cl和Br)。这些新型化合物还在2位位置含有外环氮,并且其中一些含有外环取代基:##STR1## 其中R.sub.3是较低的无环烃基团,而R.sub.4可以是H或较低的无环烃基团。本发明揭示了这些化合物的合成方法,包括展示异构和/或互变异构的化合物的合成方法。其中一些化合物具有各种农业用途(例如作为除草剂、杀虫剂、杀螨剂和杀菌剂),每个化合物都至少具有一种这样的生物学用途。本发明揭示了在植物毒性杀菌、杀螨和杀虫应用中使用这些化合物的方法。
