Certain new ar or ar' (alkylthio) benzoyl chloride phenylhydrazones have been found to be anthelmintics and active against arthropod pests. The benzoyl ring and the phenylhydrazone ring can be otherwise substituted with, for example, halogen atoms, nitro groups, .alpha.-fluoroalkyl groups, other alkylthio groups, and alkyl groups. The new compounds are prepared by reacting an ar or ar' (alkylthio) benzoic acid 2-phenylhydrazide with phosphorus pentachloride to obtain an ar or ar' (alkylthio) benzoyl chloride (dichlorophosphinyl)phenylhydrazone that is reacted with phenol to produce the desired ar or ar' (alkylthio) benzoyl chloride phenylhydrazones. Certain of the compounds can be prepared by direct halogenation of (alkylthio)benzaldehyde phenylhydrazone or an (alkylthio)benzoyl chloride phenylhydrazone. Methods of anti-arthropodal use and novel formulations for use are also described.
某些新的取代了烷硫基的苯甲酰氯苯基肼已被发现具有驱虫剂和对节肢动物害虫活性。苯甲酰环和苯肼环可以用其他基团进行替换,例如,卤素原子,硝基,α-氟烷基,其他烷硫基和烷基。新化合物是通过将芳基或烷基硫代苯甲酸2-苯基肼与五氯化磷反应,得到芳基或烷基硫代苯甲酰氯(二氯膦基)苯肼酮,然后与酚反应制得所需的芳基或烷基硫代苯甲酰氯苯基肼。其中某些化合物可以通过直接卤代(烷硫基)苯甲醛苯基肼或(烷硫基)苯甲酰氯苯基肼制备。还描述了使用的抗节肢动物方法和新型制剂。
