Aluminum hydride clusters are considered to be a promising class of energetic material. However, the synthesis of polyhedral alanes has not been achieved to date. Beta-diketiminato ligand-stabilized low valent group 13 complexes can serve as building blocks for the condensed phase synthesis of aluminum hydride clusters. Our work describes the synthesis of a series of aluminum complexes containing Β-Diketiminato ligands, which are precursors for hydrides and low valent compounds. Similar synthetic routes were also applied to boron analogues. Accordingly, aluminum compounds containing Β-diketiminato ligands [Me3CNC(Me)CHC(Me)NHCMe3] and [(DIPP)CNC(CMe3)CHC(CMe3)NH(DIPP)] have been prepared and characterized by IR and NMR spectra, and by X-ray crystallography; while expected boron compounds containing the former ligand were not formed, but two ionic compounds, [Me3CN(H)C(Me)CHC(Me)N(H)CMe3]+[Cl]- and [Me3CN(H)C(Me)CHC(Me)N(H)-CMe3]+[Br]- were obtained.
