the synthesis of a library of diverse aryl-substituted phosphanamine ligands we also found that alkyl-substituted phosphanamines can be synthesized and handled easily. This was unexpected as a previous report described them as highly air-sensitive compounds. Subsequently, we created a library of alkyl-substituted phosphanamines and found some to be highly efficient ligands in copper-catalyzed reactions
在本文中,我们公开了一种获得芳基和烷基取代的膦胺(SimplePhos 配体)的快速简便的合成方法。在合成各种芳基取代膦胺配体库的过程中,我们还发现烷基取代膦胺可以轻松合成和处理。这是出乎意料的,因为之前的报告将它们描述为对空气高度敏感的化合物。随后,我们创建了一个烷基取代的膦胺库,并发现一些是铜催化反应中的高效配体,例如铜催化的不对称共轭加成和炔丙基烷基化反应。此外,我们在合成 SimplePhos 配体方面的努力导致开发了一种简单实用的二芳基(氯)膦合成方法,本文也对此进行了介绍。
