2-(3,3-Diphenylprop-2-enyloxy)phenyllead triacetate, an arylating reagent containing an internal free radical trap, was synthesised and its behaviour studied in base-catalysed C-arylation reactions and in copper-catalysed N-arylation reactions. The absence of benzofuran derivatives among the products of C- and N-arylation reactions excludes the involvement of radical species in these two processes
