Abstract: The reaction of a pentamethylcyclopentadienyl-substituted dialane with a variety of Lewis bases results in unexpected disproportionation of the dialane into Al <superscript>I</superscript> and Al <superscript>III</superscript> species. Use of a transition-metal Lewis base allows for the formation of metal-only Lewis pairs. Furthermore, the synthesis of a Lewis base bis-adduct was successful with the Lewis base 4-dimethylaminopyridine.<br /> (© 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.)
