摘要:
Disclosed is 4-(hydrazonomethyl)benzoic acid hydrazide having the structure ##STR1## This compound can be prepared from methyl formyl benzoate and hydrazine. This compound can be prepared into a polymer by condensation with difunctional acid chlorides. Films of the polymer have unobviously high tensile and tear strengths without the necessity of biaxially orienting the film.

摘要:
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.
