The phenylation of enols and of enolate anions of ketones, β-diketones and keto esters has been studied using a range of Bi reagents.Under basic conditions C-phenylation is observed and, even hindered, perphenylated compounds are easily synthesized.Under neutral and acidic conditions ordinary ketones do not react and enolic systems give O-phenylation.A number of other anions have been phenylated under basic conditions, including the key compound indole wich mainly gave 3-C-phenylation.All these reactions can be supposed to have one of two alternative mechanisms, which parallel the two mechanisms proposed for the phenylation of phenols.

The synthesis, properties, and X-ray structures of two highly hindered polyphenylated ketones, 2,2,6,6-tetraphenylcyclohexanone and pentaphenylacetone, are described, both being obtained using bismuth(V) chemistry.
