To day, chemists synthesize cyclopropanes using pure E or Z alkenes as starting materials and usually, dangerous, unstable reagents such as diazomethane or iodomethylzinc iodide. <\/p>\n

Now, a team of researchers led by Dr. Suero at the Institute of Chemical Research of Catalonia in Tarragona (Spain) has designed a new strategy that allows the stereoconvergent preparation of trans-cyclopropanes starting from E\/Z alkene mixtures. Moreover, this photoredox catalytic method uses diiodomethane -a commercially available, easy to handle reagent- as the methylene source.<\/p>\n

This research represents the first example of a stereoconvergent cyclopropanation reaction. It is also the first proposal of a new type of carbenoid species, dubbed 'radical carbenoid', theoretically equivalent to a triplet carbene but with a completely unprecedented reactivity. <\/p>\n
