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.
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.
