The first stereoconvergent cyclopropanation reaction by means of photoredox catalysis using diiodomethane as the methylene source is described. This transformation exhibits broad functional group tolerance and it is characterized by an excellent stereocontrol en route to trans‐cyclopropanes regardless of whether E‐ or Z‐styrene substrates were utilized.
Seit römischer Zeit ist Tarragona eine Heimstätte für Entdeckungen. In dieser guten Tradition präsentieren M. G. Suero et al. in der Zuschrift auf S. 1632 ff. ein neues Reaktivitätskonzept. Beim Studium einer Photoredoxreaktion für die stereokonvergente Cyclopropanierung von Alkenen fanden sie als Schlüsselintermediat ein Iodmethylradikal, bezeichnet als radikalisches Carbenoid. Obwohl es ein Radikal...
