Min Jiang, Zhi-Cheng Mao, Zhihan Zhang, chemo-, we develop a new redox-neutral strategy that seamlessly merges photoredox and copper catalysis to enable the controlled generation of alkene radical anions and their orthogonal enantioselective cyanofunctionalization via distonic-like species. This new strategy enables highly regio-, 本期文章:《美国化学会志》:Online/在线发表 华中师范大学陈加荣团队报道了芳烃通过自由基阴离子的对映选择性氰官能化,。

relatively few synthetic applications of alkene radical anions have emerged due to a dearth of generally applicable and mild radical anion generation approaches. Precise control over the chemo- and stereoselectivity in alkene radical anion-mediated processes represents another long-standing challenge due to their high reactivity. To overcome these issues。
