Triphenylphosphine oxide is a well-known industrial waste byproduct, and thousands of tons of it are generated every year. Due to its chemical stability and limited applications, settlement of this waste issue has drawn extensive attention from chemists. The reduction of triphenylphosphine oxide to triphenylphosphine is heretofore the most employed solution, and is well reviewed. In view of our recent studies on the selective and efficient conversion of Ph₃P(O) to other valuable organophosphorus chemicals by using sodium, the present perspective mainly highlights the advances on the utilization of Ph₃P(O) to prepare a diverse range of functional organophosphorus compounds, except Ph₃P, via selective P–C, C–H, and P–O bond cleavages.

超越三苯基膦：三苯基氧化膦的利用进展

三苯基氧化膦是一种众所周知的工业废物副产品，每年产生数千吨。由于其化学稳定性和应用有限，该废物问题的解决引起了化学家的广泛关注。将三苯基膦氧化物还原为三苯基膦是迄今为止最常用的解决方案，并且得到了充分的审查。鉴于我们最近关于使用钠选择性高效地将 Ph ₃ P(O) 转化为其他有价值的有机磷化学品的研究，本观点主要强调利用 Ph ₃ P(O) 制备各种系列的进展通过选择性 P-C、C-H 和 P-O 键裂解制备功能性有机磷化合物（Ph _{3 P 除外）。}
