Abstract

Abstract : Syntheses of unique π-cyclopentadienyl bridged dialanes as complex salts with aluminate anions are reported by comproportionation of aluminocenium cations [Al III (Cp)(Cp*)] + /[Al III Cp2 ] + with [(Al I Cp*)4 ]. Abstract : Unique π-cyclopentadienyl bridged dialanes are synthesized as complex salts with aluminate anions by comproportionation of aluminocenium cations [Al III (Cp)(Cp*)] + /[Al III Cp2 ] + with [(Al I Cp*)4 ]. Very short Al–Al bond lengths occur in positively charged Al2 4+ fragments. Intriguingly, the prepared asymmetric dialane shows a unique fluxional coordination of the cyclopentadienyl ligands.
