Nitrogen and compounds

Most reactions with hydrazine are carried out with aldehydes and ketones in the presence of alkali. The reduction proper is preceded by formation of hydrazones that decompose in alkaline medium at elevated temperatures to nitrogen and compounds in which the carbonyl oxygen has been replaced by two hydrogens. The same results are obtained by alkaline-thermal decomposition of ready-made hydrazones of the carbonyl compounds. Both reactions are referred to as Wolff-Kizhner reduction [280]. [Pg.34]

The products of reaction are nitrogen and compounds B and C. Solvent effects cause significant differences in rate which are consistent with a competing ionization process. In contrast to the thermal isomerization mentioned above, the rate of thermal decomposition is insensitive to changes in substituent. Unlike the thermal isomerization reaction there is no satisfactory correlation between substituent constants and activation enthalpies or entropies. [Pg.653]
