Abstract :
The reaction of RhCl(PPh3)3 with Et2Zn easily generated a rhodium–hydride complex (Rh−H) that added to α,β-unsaturated esters to form rhodium enolate complexes by formal 1,4-reduction. These rhodium enolates gave the corresponding Reformatsky-type reagents through transmetalation, and they reacted with various aldehydes and ketones to give reductive aldol-type products in good to excellent yields.
