Abstract
Abstract The synthesis of hexa(isobutyl)dialanate with an aluminium-aluminium bond from tri(isobutyl)alane and potassium is described in the literature. We have repeated this reaction under the conditions given, but have not been able to trace the dialanate. Instead, the expected product of disproportionation, potassium tetra(isobutyl)alanate (1) was formed and isolated as the only compound. The crystal structure of 1 showed layers with the α-carbon atoms of the alanate anions bound to three different potassium cations. Furthermore, we have observed interactions of methyl group CH σ-bonds with the alkali metal.
