Abstract

The very efficient hydroacylation reaction 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 water plays an integral role in stabilizing the radical intermediate.

The reaction of hexanal and diisopropyl azodicarboxylate without catalyst under neat conditions was described by Lee et al.¹0a and afforded the addition product with 14 days at r.t.

Due to the many byproducts observed in the reaction mixture, the bisazodicarboxylates could not be isolated.¹0a

Typical Procedure for the Hydroacylation Reaction in H 2 O
To a stirred solution of aldehyde 1 (1.0 mmol) in H2O (0.5 mL) was added azodicarboxylate 2 (0.5 mmol). The reaction was stirred at r.t. for the time as indicated in Tables  [¹] and  [²] . The reaction mixture was extracted with Et2O for two times (4 × 5 mL). The Et2O solution was combined, concentrated, and purified by flash chromatography on silica gel (hexane-EtOAc = 4:1) to afford the product 3.
