Since Roman times Tarragona has been a bridge to new developments and discoveries. In this tradition, M. G. Suero et al. from the Institute of Chemical Research of Catalonia present a new reactivity concept in their Communication on page 1610 ff. While studying a photoredox approach for the stereoconvergent cyclopropanation of alkenes, they identified an iodomethyl radical, coined a radical carbenoid, as key intermediate. Although a radical, its reactivity is similar to and complements that of singlet and triplet carbenes, respectively, opening up new frontiers in carbene chemistry.
