A ligand and base-free copper catalyzed synthetic method for the efficient alpha-arylation of aromatic ketones is described. In order to avoid strong bases, ketone-derived silyl enol ethers were employed. Their reaction with diaryliodonium salts as aryl source provided the intermolecular C-C coupling...

The key to the success of this reaction is the combination of consecutive β-F elimination and C–F bond oxidative addition of a trifluoromethyl group. It also represents the first general application of α-trifluoromethyl ...
The Rh-catalyzed reaction of arylboronic acids with internal alkynes under a CO atmosphere in the presence of an acid additive afforded alpha,beta-unsaturated ketones as the major products. Hydroacylation of internal alkynes, except in the case of diaryl acetylenes, proceeded in syn fashion, ...
