    • 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.
    • 已发现某些新的ar或ar'(烷硫基)苯甲酰氯苯腙是驱虫虫,对节肢动物害虫有活性。 苯甲酰基环和苯腙环可另外被例如卤素原子,硝基,α-氟代烷基,其它烷硫基和烷基取代。 通过使芳基或芳基(烷硫基)苯甲酸2-苯基酰肼与五氯化磷反应制得新的化合物,得到与苯酚反应产生所需的Ar或Ar'(烷硫基)苯甲酰氯(二氯膦酰基)苯腙 (烷硫基)苯甲酰氯苯腙。 某些化合物可以通过直接卤化(烷硫基)苯甲醛苯腙或(烷硫基)苯甲酰氯苯腙来制备。 还描述了抗节肢动物使用方法和使用的新配方。
