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. (DOI: 10.1002/chem.201703928).
