Journal of the American Chemical Society by Yusuke Masuda, Naoki Ishida and Masahiro Murakami  /  1d  //  keep unread  //  hide  //  preview C–C bond forming carboxylation reactions of organic molecules with carbon dioxide (CO 2 ) have gained considerable attention in organic synthesis. (1) Most conventional methods including Grignard reactions and transition metal catalysis use stoichiometric amounts of reducing agents or bases. (2-4) The major driving force of these carboxylation reactions derives from the chemical reagents. Alternatively, electro- (5) or photo-assisted (6) reductive carboxylation reactions have been devised. Electron donors like triethylamine were used as the sacrificial reducing agents in most cases. Herein, we report a unique and clean carboxylation reaction that uses no sacrificial reagent but light energy as the driving force; simply upon UV irradiation of a DMSO solution of o -alkylphenyl ...

Ed. 2015, 54, 1–5  http://onlinelibrary.wiley.com/wol1/doi/10.1002/anie.201507022/full Abstract Dioxygen-tolerant [NiFe] hydrogenases catalyze not only the conversion of H 2 into 2 H + and 2 e − but also the reduction of O 2 to H 2 O. A new [NiFe]-based complex is a synthetic mimic of such hydrogenases and catalyzes O 2 reduction via an O 2 adduct, which was shown to be the first example of a side-on iron(IV) peroxo complex.
