Abstract

A metal and additional oxidant free, visible light induced decarboxylative acylation of acenaphthenone-2-ylidene ketone has been accomplished for the first time at room temperature utilizing ambient air as the only oxidant. By using 2,4,5,6-tetra(9H-carbazol-9- yl)isophthalonitrile (4CzIPN) as a photocatalyst under mild circumstance, this acylation has been carried out without the requirement of metal reagent, conventional heating and an additional base.

在金属、外加氧化剂和无碱条件下，可见光促进苊酮-2-乙基酮与α-酮羧酸的氧化脱羧酰化反应

利用环境空气作为唯一的氧化剂，首次在室温下完成了不含金属和额外氧化剂的、可见光诱导的苊酮-2-亚基酮脱羧酰化反应。在温和的环境下，使用 2,4,5,6-四（9H-咔唑-9-基）间苯二腈（4CzIPN）作为光催化剂，无需金属试剂、传统加热和额外的碱，就能进行这种酰化反应。

期刊介绍： Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry. Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters. Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
