Abstract: Synthesis and reactivity of mono- or bis-NHC-stabilized dialanes(4) (NHC)⋅Al₂Mes₄ and (NHC)₂⋅Al₂Mes₄ are reported. These compounds reveal relatively long Al−Al bonds according to their XRD structures, which was verified by DFT calculations. QTAIM analysis on (IMe^Me)₂⋅Al₂Mes₄ 7 revealed non-nuclear attractors (NNA) along the aluminum aluminum vector. First reactivity studies on (IMe^Me)₂⋅Al₂Mes₄ 7 demonstrate that NHC-ligated dialanes are thermally robust and storable synthons for the dialane(4) Al₂Mes₄. The synthesis of (IMe^Me)⋅AlClMes₂ 10, {(IMe^Me)⋅AlMes₂}₂-E (E=O 11, S 12), and the dimetallaacetylide {(IMe^Me)⋅AlMes₂}₂-μ-(C≡C) 13 is reported starting from 7.
