Lewis‐Base‐Induced Disproportionation of a Dialane

Abstract

The reaction of a pentamethylcyclopentadienyl-substituted dialane with a variety of Lewis bases results in unexpected disproportionation of the dialane into Al^I and Al^III 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.
