Abstract

Abstract: The synthesis of a hexacoordinate triorganoaluminum compound Al(NapSiH)3 (6 ) (NapSiH = 8‐dimethylsilylnaphthyl) is reported. Three additional Si–H··· Al contacts complete the coordination sphere around the central aluminum atom. Structural and spectroscopic evidence is provided for an activation of the Si–H bond by the aluminum Lewis acid. This activation is however small when compared to other recently described aluminum / silane complexes. These findings are supported by the results of quantum mechanical calculations, which indicate the presence of three Si–H··· Al three center intractions in complex6 . Abstract :
