Trinuclear scandium methylidyne complexes stabilized by pentamethylcyclopentadienyl ligands

Abstract

The first examples of scandium methylidyne complexes [(Cp*)Sc(μ₂-X)]₃(μ₃-CH) (Cp* = C₅Me₅; X = Br, Me, OMe), free of Lewis acids, can be achieved in high yields from [(Cp*)ScMe₂]₂ through a facile route. The chemical and geometrical flexibility to incorporate organic substrates indicates a rich chemistry of complex [(Cp*)Sc(μ₂-OMe)]₃(μ₃-CH).
