Carbyne transfer Marcos G. Suero and his research group at the Institute of Chemical Research of Catalonia (ICIQ; Tarragona, Spain; www.iciq.es) have reported a new reaction that inserts a monovalent carbon unit between both sp2-hybridized carbons of alkenes. For the reaction, the chemists developed a first catalytic generation of rhodium-carbynoids, which emulate the carbene/carbocation behavior of a monovalent cationic carbyne. The catalytic generation of Rh-carbynoids represents a new platform for carbyne transfer that enables skeletal remodeling, and circumvents a long-standing challenge in the catalytic generation of metal-carbynes. Aside from inserting a new monovalent carbon atom, the reaction also introduces extra complexity in the molecule: a single C–C bond and a double C–C bond are created together with a chiral center at one of the C atoms with the cleaved double bond. The skeletal editing will allow building complex architectures, thus expanding the synthetic possibilities of creating new materials or medicines. The findings are described in the September 12 issue of the J. Am. Chem. Soc.
