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. 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 hydrocarbon group of from 5 to 12 carbon atoms connected to the carbonyl group through an oxygen or a sulfur atom. The compounds are generally prepared by contacting a 1-unsubstituted benzimidazole with a hydrocarbon radical substituted chloroformate or chlorothiol formate.
新的苯并咪唑衍生物在1-位置以羰基取代物和在2-位置以4-噻唑基团取代物是有效的杀真菌剂和驱虫药。描述了这些化合物以及它们的制备方法,还描述了用于它们的使用的抗真菌和驱虫药组合物。1-位置取代基是一个由5到12个碳原子组成的碳氢基团,通过氧原子或硫原子连接到羰基。这些化合物通常是通过将1-未取代的苯并咪唑与烃基取代的氯甲酸酯或氯硫酸酯接触而制备的。
