ABSTRACT:
A process for producing dimeric unsaturated aldehydes from alpha, beta unsaturated aldehyde is disclosed. This process is conducted by contacting the alpha, beta unsaturated aldehyde with a copper (II) catalyst and a complexing amine catalyst in a medium with a relatively high dielectric constant in substantially anhydrous and aprotic conditions.
