New Azoolefines and their Acidic Cleavage to Aryldiimines

3-Amino-1-aryl-3',3'-dimethyl-pyrazolin-4-spiro-2'-oxiran-5-ones (3a-c) undergo ring opening with methoxide forming methyl 3-amino-3-arylazo-propenoates (5a-c). 5a-c are cleaved under acidic conditions.The main products of the cleavage of 5c with methanolic hydrochloric acid are nitrogen, 2,4,6-trichloro-benzene (6), 2,4,6-trichloro-aniline (9) and 2,4,6-trichloro-phenylhydrazine (10).Intermediates of the cleavage of 5 are aryldiimines trapped with benzaldehyde as the corresponding benzhydrazides (12a,b).

Method of use, composition, and compounds

Certain benzoyl chloride phenylhydrazones have been found to be active against insects and mites. The benzoyl ring and the phenylhydrazone ring can be substituted with a halogen atom, a nitro group, or an alkyl group of from 1 to 6 carbon atoms, inclusive
