CarboranfunktionalisierungIn der Zuschrift auf S. 8768 ff. berichten Z. Xie et al. über die erste übergangsmetallfreie nucleophile Substitutionsreaktion an den Käfig‐B‐H‐Bindungen von o‐Carboranen mit Grignard‐Reagentien.
Direct nucleophilic substitution reaction of cage B−H bonds of o‐carboranes by Grignard reagents in the absence of any transition metals has been achieved for the first time, and leads to the regioselective synthesis of a series of 4‐alkyl‐1,2‐diaryl‐o‐carboranes in very high yields. The presence of two electron‐withdrawing aryl groups on the cage carbon atoms is crucial to realizing the reaction...
