1,2-di-n-butylhydrazine in hexane solution has been oxidized to azo-n-butane with oxygen and Pd/C catalyst and with red mercuric oxide.Both methods led to the same calculated heat of hydrogenation (ΔHH) of the azo group in hexane, -16.4 +/- 0.3 kcal/mol.This value is 10.6 kcal/mol less exothermic than the ΔHH of carbon-carbon double bonds.

Reactions of alkyl halides with azines of p-nitrobenzaldehyde, benzaldehyde, and p-methoxybenzaldehyde at a high pressure (10 kbar) were studied. Hydrolysis of the reaction mixtures gives pure N-monoalkyl- or N,N′-dialkylhydrazines in high yields, depending on the structure of the starting azine and the solvent nature. It was found that non-symmetrical N,N′-dialkylhydrazines can be synthesized without isolating intermediate N-monoquaternary immonium salts. The effect of the phase transition of the solvent on the direction of the alkylation is discussed.
