摘要/Abstract

可见光促进的有机合成是近年来有机化学领域重要的研究热点和前沿.其中，廉价易得的有机染料作为光催化剂的应用引起了人们的关注.近来，2，4，5，6-四（9-咔唑基）间苯二腈（4CzIPN）作为一种新型的有机光敏剂，在可见光诱导的自由基反应中表现出优异的催化性能.主要综述了可见光诱导下4CzIPN催化的无金属有机光合成反应，介绍了4CzIPN引发不同类型自由基前体（包括硅试剂、羧酸及其衍生物、含硫试剂和氟试剂等）的光合成应用.

Visible-light-promoted organic synthesis is an important research hotspot and frontier in organic chemistry in recent years. Particularly, as a novel organic photosensitizer, 2, 4, 5, 6-tetrakis(carbazol-9-yl)-1, 3-dicyanobenzene (4CzIPN) has showed excellent catalytic performance in visible-light-induced radical reactions. The recent progress on the transition-metal-free photosynthesis under visible-light catalyzed by 4CzIPN is reviewed, and the application of 4CzIPN for photocatalytic organic transformations from different precursors (including silicon reagent, carboxylic acid and its derivatives, sulfur-containing reagent and fluorine reagent) is included.
