The phenylation of a variety of phenols by pentavalent bismuth reagents under neutral, acid and basic conditions has been investigated.Under basic conditions well defined pentavalent intermediates have been isolated and fully characterised.Their decomposition gives only ortho-C-phenylation (except in the case of a p-nitrophenol derivative).O-Phenylation is seen under neutral or acidic conditions.Another mechanism is proposed to explain this reaction with no pentavalent bismuth intermediate.

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 include nitrocompounds and amides.
