protonolysis) of aluminium hydrides with amines is a common method to make Al-N bonds, these reactions can suffer from slow reaction rates and often salt-metathesis methods are preferred. 8 For substrates containing more than one Al-H bond achieving a selective reaction is also a potential problem. 40Catalytic approaches to the dehydrocoupling of amines and alanes offer an opportunity to address the issue of selectivity while vastly increasing reaction rates, to the best of our knowledge catalysts for this reaction remain unreported. Herein we report our initial findings on the thermal and catalytic

Man nehme zwei Metalle: Vierfach koordinierte Aluminiumdihydride wie 1 sind das Reduktionsmittel in der selektiven Titelreaktion. Der Heterodimetallkomplex 2 wurde isoliert und als katalytisch aktive Spezies identifiziert.
