Aromatic α,β-unsaturated ketones are synthesized efficiently by
palladium-catalyzed cross-coupling reaction of arylboronic acids with
α,β-unsaturated acyl chlorides in the presence of K3PO4
hydrate in toluene.

A new method for the synthesis of organoborates starting from α,β-unsaturated
acetals was developed. The available alkoxy-functionalized butadienyl- and
styrylboronic esters cross couple effectively with a broad spectrum of aryl
halides under mild conditions. This method provides an effective
approach to aromatic ketones.

A regioselective intermolecular hydroacylation of vinalarenes, in which
symmetric and mixed carboxylic anhydrides are used as acyl donors, is
promoted by a cationic rhodium catalyst ligated by triphenylarsine.
