Abstract

Abstract : Room temperature decarboxylative annulation of benzoic acids with alkynes to produce substituted naphthalenes has been achieved by using an electron‐deficient (η5‐cyclopentadienyl)rhodium(III) [CpERhIII] complex. The electron‐deficient nature of the CpERhIII catalyst would cause the strong rhodium–π interaction, which accelerates the decarboxylation as well as the C−H bond cleavage. This low temperature carbon dioxide generation is compared to a beer dispenser. More information can be found in the Communication by Y. Shibata, K. Tanaka et al. onpage 317 .
