Pentaphenylbismuth is a useful reagent for the specific ortho-phenylation of phenols under very mild conditions, a comparison of this reagent with triphenylbismuthcarbonate being drawn; arylationreactions of the carbonate have been extended to include nitro-compounds and amides.

Phenols and naphthols are dearomatized to methoxycyclohexadienones under simple and robust electrochemical conditions, in a green way without chemical oxidants. The mechanism of the reaction is established using density functional theory calculations, which also explain the chemo- and regioselectivity for differently-substituted substrates.
