The reaction of aryllead(IV) triacetates with benzofuran-3(2H)-one 1 yields the 2,2-diarylated ketone or the monoarylated ketone with the hindered lead reagent 15. 2-Phenylthiobenzofuran-3(2H)-one 2 was easily arylated with a wide range of aryllead reagents to give arylated ketones in 29-92% yields. Alpha-acetoxylation was observed only as a side reaction with hindered lead reagents, bearing ortho-substituents.
