Herein, we report a novel, molecularly defined NNN-type cobalt pincer complex catalyzed transfer semi-hydrogenation of unbiased alkynes to Z-selective alkenes. This unified process is highly stereo- and chemo-selective and exhibits a broad scope as well as wide functional group tolerance. Ammonia-borane (AB), a bench-stable substrate with high gravimetric hydrogen capacity, was used as a safe and practical transfer hydrogenating source.

无磷的钴夹钳络合物催化无偏炔的Z选择性半氢化†

在本文中，我们报道了一种新颖的，分子定义的NNN型钴夹钳络合物，可将无偏炔烃转移至Z选择性烯烃的转移半氢化反应。这种统一的过程具有高度的立体选择性和化学选择性，并具有广泛的功能范围和广泛的官能团耐受性。氨硼烷（AB）是一种具有高重量氢容量的台式稳定底物，被用作安全实用的转移加氢源。
