| Tropos and atropos biaryl diphosphines have been prepared in a stepwise highly regioselective double Diels-Alder cycloaddition-elimination sequence between 1,4-bis(diphenylphosphinoyl)buta-1,3-diyne and various 1,3-dienes; the unsymmetrical phosphine 2,6´-bis(diphenylphosphino)-2´-methoxy-1,1´-biphenyl prepared using this approach forms an efficient catalyst for the amination of a range of aromatic bromides, giving conversions that rival those obtained with its BIPHEP counterpart. |
