Inside Back Cover: Visible-Light-Induced Click Chemistry (Angew. Chem. Int. Ed. 35/2015)

An ultrarapid visible-light-driven method for catalyst-free ligation is reported. In their Communication on page 10284 ff., C. Barner-Kowollik and co-workers describe a highly efficient conjugation between an azirine moiety (white) and diverse dipolarophiles (red) under irradiation from blue LEDs. Following the photogeneration of a nitrile ylide (cyan structure), complete conversion into the cycloadduct takes place through a click-type reaction
