  对称和混合三(酰基)膦：合成、氧化和光化学

  摘要：

  对称和混合三（酰基）膦：在这篇文章中，我们提出了一种方便的合成程序，从红磷开始到三（酰基）膦（TAP），再到三（酰基）氧化膦（TAPO）。几种合成的 TAP 表现出膦-磷烯平衡，对此进行了详细研究。一些选定的 TAP 的氧化产生了相应的 TAPO，并作为潜在的光引发剂进行了测试。

• Aroylphosphanes: Base‐Free Synthesis and Their Coordination Chemistry with Platinum‐Group Metals

  weight of evidence suggests negligible contribution from this canonical form. Comparison is drawn to the structurally characterised O=P(C6H5Me-2)3 (8) in which the lone pair is sequestered. The coordination of 2–5 to rhodium(I), palladium(II) and platinum(II) is described, affording rare examples of aroylphosphane complexes of the platinum-group metals.

  通过各自的芳酰氯和HPPh2的无碱缩合，已经以良好的收率制备了一系列芳酰膦。除了环烷 m--C(O)- C6H4(C(O)PMe)}2 (1)，C6H4RC(O)PPh2} (R = 3-Me 2, 3-CH2Cl 3, 4-CO2Me 4, 4-CN 5) 和双（芳酰基膦）C6H42,6-C(O)PPh2}2 (6) 和 C6H3N2,6-C(O)PPh2}2 (7 )符合“磷酰胺”特征的表现；然而，大量证据表明这种规范形式的贡献可以忽略不计。与结构特征的 O=P(C6H5Me-2)3 (8) 进行比较，其中孤对被隔离。描述了 2-5 与铑 (I)、钯 (II) 和铂 (II) 的配位，提供了铂族金属的芳酰基膦配合物的罕见例子。
