Abstract

The potassium aluminyl complex K₂[Al{N(Dipp)SiMe₃}₂]₂ was synthesised via reduction of [AlI{N(Dipp)SiMe₃}₂] (Dipp = 2,6-i-Pr₂C₆H₃). This represents the first example of an aluminyl anion supported by an acyclic ligand framework. Attempts to yield the same structure with a larger ligand framework, {N(Dipp)Si(i-Pr)₃}, led to C-H cleavage. K₂[Al{N(Dipp)SiMe₃}₂]₂ behaves as a nucleophilic source of aluminium; reaction with an electrophilic β-diketiminate supported magnesium(ii) iodide forms a monomeric, acyclic magnesium aluminyl complex.
