  1,3-二苯基二硅氧烷化学选择性还原氧化膦

  摘要：

  将氧化膦还原为相应的膦是制备这些有价值的试剂的最直接的方法。然而，由于P=O键的强度和/或较差的原子经济性，现有的还原氧化膦的方法存在化学选择性不足的问题。在此，我们报告了迄今为止用于这种​​转化的最强大的化学选择性还原剂的发现，1,3-二苯基二硅氧烷（DPDS）。无添加剂的DPDS选择性还原仲膦氧化物和叔膦氧化物，即使存在醛、硝基、酯、α,β-不饱和羰基、偶氮羧酸酯和氰基官能团，也能保持构型。阿累尼乌斯分析表明， DPDS还原的活化势垒明显低于任何先前计算的硅烷还原系统。催化布朗斯台德酸的加入进一步降低了活化能垒，并首次在室温下实现了硅烷介导的无环氧化膦还原。
