Carbonylative 1,4-addition of potassium aryltrifluoroborates to vinyl ketones

Potassium aryltrifluoroborates have proven to be useful reagents for the carbonylative aroylation of vinyl ketones; this study broadens the scope of potassium aryltrifluoroborates in homogeneous catalysis and shows that the solvent can act as the proton source for this family of reactions.
