Photocatalytic decarboxylative coupling between α-oxocarboxylicacids and alkenes
2019
Photocatalytic decarboxylative cross-coupling which achieves the derivatization of widespread organic acids has become a hot topic in organic synthesis. As special acids, α-oxocarboxylicacids show the great potential in running decarboxylation to construct ketone derivatives. In this article, we have developed a photocatalytic decarboxylative cross-coupling of α-oxocarboxylicacids and olefins to the synthesis of diverse aryl ketones. Various alkenes and α-oxocarboxylicacids were compatible, generating the desired products in up to 90% yield. Preliminary mechanism studies suggest that a free radical pathway is involved in this process.
