  一级，二级和三级膦的革兰氏级合成的通用方法

  摘要：

  尽管有机膦的合成在一个世纪的上半叶已广为人知，但是即使对于资深的合成化学家来说，膦的合成仍然代表着艰巨的任务。膦作为一类化合物，其对空气的敏感性差异很大，并且误以为新手化学家尝试看似简单的合成是微不足道的，甚至是容易的，这会带来灾难性的结果。为了简化任务，我们之前已经开发出一种使用台式中间体访问各种氧化膦（膦的直接前体）的方法。这种合成方法可以节省无空气的处理，直到最后一步（还原并分离出膦）。本文介绍了将膦酸酯，次膦酸酯和膦氧化物轻松还原为伯，仲，和叔膦使用氢化铝还原剂。亲电还原剂（i Bu） 2 AlH和AlH 3在还原选择性和反应性方面被确定大大优于LiAlH 4。值得注意的是，即使LiAlH 4和（ i Bu） 2 AlH不能，AlH 3仍能还原具有极强抗性的三环己基氧化膦。使用这种新方法，可以以克级反应合成出代表性范围的伯，仲和叔膦（包括挥发性膦），而无需纯化步骤，可实现出色的收率和无与伦比的纯度。

  A rapid method for the reduction of secondary phosphine oxides under mild conditions has been developed, allowing simple isolation of the corresponding free phosphines. The methodology involves the use of pinacol borane (HBpin) to effect the reduction while circumventing the formation of a phosphine borane adduct, as is usually the case with various other commonly used borane reducing agents such as

  Various cyclic phosphonium structures are formed in high yield by the deprotection of unstable phosphine-aldehydes in acidic solution. When there is a methylene spacer between the phosphine and the aldehyde, a phosphonium ion [PHR2CH2CH(OEt)2]Br2, R=iPrOH, Et is obtained. Reaction of these phosphonium salts with water produces the dimers [–PR2CH2CH(OH)–]2[Br]2 R = iPr, Et. When there is an ethylene

  We present the first base‐free Fe‐catalyzed ester reduction applying molecular hydrogen. Without any additives, a variety of carboxylic acid esters and lactones were hydrogenated with high efficiency. Computations reveal an outer‐sphere mechanism involving simultaneous hydrogen transfer from the iron center and the ligand. This assumption is supported by NMR experiments.

  我们展示了第一个使用分子氢的无碱铁催化的酯还原反应。在没有任何添加剂的情况下，各种羧酸酯和内酯被高效地氢化。计算揭示了一种外球机理，涉及同时从铁中心和配体转移氢。NMR实验支持这一假设。
