Aryl boronic acids 2a-d and la-d obtained by metalation-B(OMe)s or metalation silylation-ipso borodesilylation sequences, participate in efficient Pd'-catalyzed cross coupling reactions with aryl bromides to give unsymmetrical biphenyls 3a-d and m\_terphenyls 5a-d respectively. We have recently des
