New benzimidazoles substituted at the 1-position with carbonyl substituents and at the 2-position with a 4-thiazolyl group are effective fungicides and anthelmintics exhibiting particularly useful hydrophilic and lypophilic effects. The compounds as well as processes for their preparation are described along with antifungal and anthelmintic compositions for their use. The 1-position substituent is a loweralkoxy or phenylloweralkoxy substituted ethoxy or polyethoxy carbonyl group of a chain with up to 4 ethoxy groups connected to the carbonyl. The compounds are generally prepared by contacting a 1-unsubstituted benzimidazole with a loweralkoxy or phenylloweralkoxy substituted ethoxy or polyethoxy chloroformate.
在1-位置带有羰基取代基,并在2-位置带有4-噻唑基团的新苯并咪唑类化合物是有效的杀菌剂和驱虫剂,具有特别有用的亲水和亲脂效果。描述了这些化合物以及它们的制备过程,还描述了用于它们的抗真菌和驱虫剂组合物的用途。1-位置的取代基是链上带有最多4个乙氧基与羰基连接的低烷氧基或苯基低烷氧基取代乙氧基或聚乙氧基羰基。通常通过将1-未取代的苯并咪唑与低烷氧基或苯基低烷氧基取代的乙氧基或聚乙氧基氯甲酸酯接触来制备这些化合物。
