摘要：

A mixture of palladium(0) and CATPHOS, the 1,3-butadiene-bridged diphosphine generated via double Diels-Alder cycloaddition between bis(diphenylphosphinoyl)butci-1,3-diyne and anthracene, catalyzes the amination of a range of aromatic bromides as well as the alpha-arvlation of ketones, giving conversions that either rival or exceed those obtained with BINAP.
