[GRAPHICS]Potassium alkenyl- and aryltrifluoroborates undergo addition to enones and aldehydes in the presence of Rh(1) catalysts to give beta-functionalized ketones and allylic/benzylic alcohols, respectively. Reaction proceeds more rapidly than with the corresponding boronic acids, and the choice of phosphine ligand does not signifcantly influence the overall efficiency of addition.
