Further examples of the selectivity of pentavalent trianyl-organobismuth oxidants are presented; deuterium labelling studies have established that the mechanism of oxidation of allylic alcohols by these reagents involves, to some extent, cleavage of

Pentaphenylbismuth is a useful reagent for the specific ortho-phenylation of phenols under very mild conditions, a comparison of this reagent with triphenylbismuth carbonate being drawn; arylation reactions of the carbonate have been extended to incl

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
