要旨

The irradiation of chromone-2-carboxylic esters with a blue LED in the presence of Rose Bengal and triethanolamine (TEOA) is used to obtain 2,2′-bichromanone of methyl, ethyl, n-propyl, iso-propyl, n-butyl, n-pentyl, and n-hexyl chromone-2-carboxylic esters in 52–93% yield and drtrans : cis up to 83 : 17. The key role played by Rose Bengal, TEOA, and blue light was established through numerous control experiments and a plausible mechanism is discussed.

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
