biaryls in up to 92% yield. Arylhalides also undergo POPd7-catalyzed aryl-vinyl and aryl-alkyl bond formation under mild conditions. Styrenes and alkylarenes were prepared in 79-93% yield fromarylhalides and vinyl or alkylzinc reagents. The replacement of arylhalides by acyl halides provides access to ketones which were produced in up to 98% yield when POPd was used as catalyst. This approach overcomes
