photoredox catalysis (PC) and hydrogen atom transfer (HAT) catalysis have received increasing attention. Here, we report a Ph2GeCl2 cocatalyst that greatly improves the yield of α-C(sp3)–H alkylation of primary amines catalyzed by a PC-HAT hybrid system. The α-position of the amino group selectively reacted even when weaker C–H bonds existed in the substrates. This finding may help the design of a novel
使用光氧化还原催化 (PC) 和氢原子转移 (HAT) 催化的位点选择性 C(sp 3 )–H 功能化已受到越来越多的关注。在这里,我们报道了一种 Ph 2 GeCl 2助催化剂,它极大地提高了由 PC-HAT 混合系统催化的
伯胺的 α-C(sp 3 )-H 烷基化的产率。即使底物中存在较弱的 C-H 键,
氨基的 α 位也会选择性地发生反应。这一发现可能有助于设计一种新型的位点选择性混合催化剂。
