The unsymmetrically disubstituted hydrazines 1 were condensed with carbonyl compounds.Some of the expected condensation products were isolated, but some were formed as unstable intermediates which underwent 1,4-elimination: The phenylhydrazone of the carbonyl compound used was obtained, together with the corresponding phenylazo-alkene 11 or alternatively, the 1,4-addition product of a different protic nucleophile to 11.

The addition of phenylhydrazine to phenylazo-alkenes 4 yields α-(1-phenylhydrazino)-phenylhydrazones 1.The reaction of phenylhydrazine with α-halogenated carbonyl compounds 5 affords either 1 or the isomeric α-(2-phenylhydrazino)-phenylhydrazones 2.Struct
