Schantl, Joachim G.,Karpellus, Peter,Prean, Michael

, p. 5807 - 5814 (1987)

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.
