Abstract

A facile visible-light-induced 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN) catalyzed four-component reaction of alkenes, quinoxalin-2(1H)-ones, P₄S₁₀ and alcohols has been developed at room temperature. This tandem reaction provides an efficient strategy for the construction of various phosphorodithioate-containing quinoxalin-2(1H)-ones with moderate to good yields by using air (dioxygen) as the green oxidant. Experimental studies revealed a radical process was involved in this photochemical reaction.

可见光诱导烯烃的四组分双官能化，构建含磷二硫酸盐的喹喔啉-2(1H)-酮

研究人员在室温下开发了一种简便的可见光诱导 1,2,3,5-四(咔唑-9-基)-4,6-二氰基苯（4CzIPN）催化烯类、喹喔啉-2(1H)-酮、P4S10 和醇的四组分反应。这种串联反应提供了一种高效的策略，利用空气（二氧）作为绿色氧化剂，可以中等至良好的收率生成各种含二硫代磷酸酯的喹喔啉-2(1H)-酮。实验研究表明，这一光化反应涉及一个自由基过程。
