  PIII/PV═O 氧化还原催化连续等线反应脱氧氧化膦

  摘要：

  氧化膦的脱氧对于磷配体和相关催化剂的合成以及磷化学的可持续发展具有重要意义。然而，P=O键的热力学惰性对其还原提出了严峻的挑战。以前在这方面的方法主要依赖于在恶劣条件下使用路易斯/布朗斯台德酸或化学计量卤化试剂进行的 P=O 键活化。在这里，我们希望报告一种通过连续的等糖反应轻松有效地氧化膦脱氧的新催化策略，其断裂强P=O键的热力学驱动力通过同步形成另一个P=O键来补偿。该反应是通过P III /P=O氧化还原序列与环状有机磷催化剂和末端还原剂PhSiH 3实现的。该催化反应避免了其他情况下使用化学计量活化剂，具有底物范围广、反应活性优异、反应条件温和的特点。初步的热力学和机理研究揭示了催化剂的双重协同作用。

  A Study of the Aryl–Aryl Coupling Reactions of (4‐X‐C₆H₄)Ph₂P˭O

  摘要：

  The Suzuki coupling reactions of (4-X-Ph)Ph2P=O, where X = bromide or triflate, with a series of boronic acids were studied using tetrakis-(triphenylphosphino) palladium or palladium acetate as the catalyst. The boronic acids utilized were phenyl, p-tolyl, 3-methoxy, 4-methoxy, and 4-acetyl. Yields of the corresponding biphenyl analogues ranged from 50 to 95%. Palladium acetate provided products free of triphenylphosphine contamination, and required significantly shorter reaction times for complete reaction (2 to 4 hours vs. 12 to 24 hours, respectively) than when tetrakis-(triphenylphosphino) palladium was used. The methodology was applied to bis(4-F-Ph)(4-OTf-Ph)P=O to afford, in excellent yield (99%), a biphenyl-based AB, monomer precursor for dendritic and hyperbranched poly(arylene ether phosphine oxide)s.
