The Intermetalloid Cluster [(CpAlCu)6H4], Embedding a Cu6 Core Inside an Octahedral Al6 Shell: Molecular Models of Hume-Rothery Nanophases

Defined molecular models for the surface chemistry of Hume–Rothery nanophases related to catalysis are very rare. The Al‐Cu intermetalloid cluster [(Cp*AlCu)6H4] was selectively obtained from the clean reaction of [(Cp*Al)4] and [(Ph3PCuH)6]. The stronger affinity of Cp*Al towards Cu sweeps the phos...

Description
Summary:Defined molecular models for the surface chemistry of Hume–Rothery nanophases related to catalysis are very rare. The Al‐Cu intermetalloid cluster [(Cp*AlCu)6H4] was selectively obtained from the clean reaction of [(Cp*Al)4] and [(Ph3PCuH)6]. The stronger affinity of Cp*Al towards Cu sweeps the phosphine ligands from the copper hydride precursor and furnishes an octahedral Al6 cage to encapsulate the Cu6 core. The resulting hydrido cluster M12H4 reacts with benzonitrile to give the stoichiometric hydrometalation product [(Cp*AlCu)6H3(N=CHPh)]. Aluminum–copper cluster: The novel intermetallic cluster [(Cp*AlCu)6H4] was selectively obtained from the reaction of [Cp*Al]4 and [Ph3PCuH]6. The stronger affinity of Cp*Al towards Cu sweeps the phosphine ligands from the hydride derivative and furnishes an octahedral Al6 cage to encapsulate the Cu6 core. The hydrido cluster M12H4 reacts with benzonitrile to give the stoichiometric insertion product [(Cp*AlCu)6H3(N=CHPh)].
