摘要

在水的存在下，开发了一种方便的烯烃、喹喔啉-2(1H)-酮和重氮化合物的多组分光催化反应。在室温条件下，可以有效地获得一些含酯的喹喔啉-2(1H)-酮，收率从中等到良好。这种无金属可见光驱动的串联反应是通过质子耦合电子转移（PCET）过程进行的，使用水作为氢供体，1,2,3,5-四（咔唑-9-基）-4,6-二氰基苯（4CzIPN）作为光催化剂。

Photocatalytic multi-component synthesis of ester-containing quinoxalin-2(1H)-ones using water as the hydrogen donor

A convenient photocatalytic multi-component reaction of alkenes, quinoxalin-2(1H)-ones, and diazo compounds has been developed in the presence of water. A number of ester-containing quinoxalin-2(1H)-ones could be efficiently obtained in moderate to good yields at room temperature. This metal-free visible-light-driven tandem reaction was conducted through proton-coupled electron transfer (PCET) process using water as the hydrogen donor and 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN) as the photocatalyst.
