Hydrogenation of hydrazones

Hydrogenation of hydrazones and azines is a useful way to prepare hydrazine derivatives. The hydrogenation may proceed further to amines depending on the structure of compound, catalyst, and reaction conditions. Unsubstituted hydrazones (I) are liable to hydrolysis, especially with the hydrazones derived from ketones in acidic media and slow hydrogenation. The ketones thus formed may afford azines (II) by condensation with the parent hydrazones. Hydrogenation of azines affords symmetrically... [Pg.305]
