The use of frustrated Lewis pairs is an extremely important approach to metal-free hydrogenations. In contrast to the rapid growth of catalytic reactions, asymmetric hydrogenations are far less developed due to a severe shortage of readily available chiral frustrated Lewis pair catalysts with high catalytic activities and selectivities. Unlike the stable Lewis base component of frustrated Lewis pairs, the moisture-sensitive boron Lewis acid component is difficult to prepare. The development of convenient methods for the quick construction of chiral boron Lewis acids is therefore of great interest.

沮丧的路易斯对催化的不对称无金属加氢和氢甲硅烷基化反应

沮丧的路易斯对的使用是无金属氢化的极其重要的方法。与催化反应的快速增长相反，由于严重缺乏容易获得的具有高催化活性和选择性的手性失意的路易斯对催化剂，因此不对称氢化的发展远远不如前者。不同于沮丧的路易斯对的稳定的路易斯碱组分，对水分敏感的硼路易斯酸组分难以制备。因此，快速构建手性硼路易斯酸的简便方法的开发引起了极大的兴趣。
