摘要：

A series of functional bisphosphosphine oxides were synthesized in good yields via new Pd-catalyzed bis-hydrophosphinylation reactions of terminal alkynes and diphenylphosphine oxide. The resulting bisphosphine oxides were reduced to their corresponding bisphosphines in quantitative yields via a Ti((OPr)-Pr-i)(4)-mediated process. (C) 2002 Elsevier Science Ltd.
