A conjugate addition of arylboronic acids to alpha,beta-unsaturated carbonyl compounds catalyzed by 2 beta-CD-[Rh(OH)(cod)](2) or [RhCl(cod)](2) in a single aqueous medium
The rhodium-catalyzed conjugate addition of tolylboronic acid to alpha,beta -unsaturated ketones, esters or amides was carried out in water. [RhCl(cod)](2) and 2 beta -cyclodextrin-[Rh(OH)(cod)](2) complexes were found to catalyze the reaction efficiently in a single aqueous medium.
