Scandium─Group 13 Heterobimetallic Methylidene Clusters.

ABSTRACT: A straightforward synthesis of Cp*₂Sc(AlMe₄) (Cp* = C₅Me₅) applying Cp*₂ScCl(thf) and LiAlMe₄/AlMe₃ is described. Donor-assisted trimethyltriel exchange gives access to Cp*₂Sc(EMe₄) (E = Ga, In), which represent the first scandium tetramethylgallate and tetramethylindate complexes. Thermal treatment of Cp*₂Sc(EMe₄) (E = Ga, In) in benzene leads to the isolation of methylidene clusters Cp*₆Sc₄E₈(CH₂)₁₂Me₆ (E = Ga, In). This methyl group deprotonation differs from the benzene activation previously observed for Cp*₂Y(EMe₄) (E = Al, Ga). Treatment of Cp*₂Sc(EMe₄) (E
