Visible-light-triggered carbon−heteroatom cross-coupling reactions without exogenous photocatalysts were realized using a nickel catalyst that was activated through intraligand charge transfer. Ligand polymerization afforded a porous, recyclable organic polymer for heterogeneous nickel catalyzed cross-coupling reactions. The heterogeneous catalyst demonstrates stable performance in a packed-bed flow
使用通过配体内电荷转移激活的镍催化剂实现了可见光触发的碳-杂原子交叉偶联反应,无需外源光催化剂。配体聚合为多相镍催化的交叉偶联反应提供了一种多孔、可回收的有机聚合物。在连续运行一周的过程中,多相催化剂在填充床流动反应器中表现出稳定的性能。
