Zn(OAc)2·2H2O is found to be an effective catalyst for the hydroacylation reaction of azodicarboxylates with aldehydes. A wide range of aldehydes, including aliphatic, aromatic and heterocyclic compounds, was considered. Most of the hydroacylation reactions afforded the hydroacylation products in good to excellent yields. The overall system is simple, economical and has practical advantages for construction of carbon-nitrogen bonds.
The hydroacylationreaction of aldehydes with azodicarboxylates catalyzed by copper(II) acetate monohydrate has been reported. The reaction of various aldehydes gave the corresponding hydroacylation products in 60–98% yields under mild conditions. The method is simple, economical, and has practical advantages for the construction of the carbon–nitrogen bonds.

We describe a green and efficient procedure for the hydroacylation of aldehydes with diisopropyl azodicarboxylate, using CuO nanoparticles supported on silica (CuO-np/SiO2) as a catalyst, in good to excellent yields. A wide range of aldehydes, including aromatic and aliphatic compounds, were considered. The catalyst is found to be truly heterogeneous in the reaction mixture and can be reused without loss of catalytic activity.
The very efficienthydroacylationreaction of azodicarboxylates, with various aldehydes, was carried successfully out at room temperature in water without the use of a catalyst to obtain a variety of hydrazine imide products in high yields. A wide range of aldehydes, including aliphatic and aromatic compounds, was considered, and the reaction is believed to proceed via a radical mechanism, in which

Abstractmagnified imageThe highly efficient hydroacylation reaction of aldehydes with azodicarboxylates has been carried out in the ionic liquid,1‐n‐butyl‐3‐methylimidazolium bis(trifluoromethanesulfonyl)imide, [BMIM] [NTf2]. The products were readily separated by extraction from the reaction medium and the ionic liquid could be recycled up to 8 times and the yields of the reactions were not affected. Compared to conventional solvents, high yields were achieved with aliphatic saturated aldehydes, and the reaction can be conducted under normal to mild conditions without the use of a catalyst.
