Kurzfassung:
The selective formation of homonuclear bonds is of key importance in synthetic chemistry. Especially, dehydrocoupling reactions are attractive as ecologically and economically friendly alternatives to established reductive bond forming reactions, since they do not require the use of stoichiometric amounts of a reducing reagent and produce only valuable dihydrogen as by‐product. Here, we report on a metal‐free B−B dehydrocoupling reaction that starts directly from a simple, easily accessible BH 3 adduct, providing convenient access to a new nucleophilic dihydridodiborane in excellent yield. The dihydridodiborane in turn activates dihydrogen, allowing to obtain quantitatively the dideuteridodiborane from the dihydridodiborane by D 2 activation. On the basis of detailed quantum‐chemical calculations, the mechanism of this unprecedented reaction is elucidated. Some key points that are essential for metal‐free dehydrocoupling are disclosed, paving the way for their systematic evaluation and application.
