Abstract

A series of new scandium complexes supported by the phthalocyanine (Pc) ligand have been prepared and structurally characterized. Reaction of ScCl₃ with phthalonitrile affords a mixture of PcScCl (1) and unreacted ScCl₃, which upon addition of LiCH(SiMe₃)₂ yields THF-soluble PcSc(μ-Cl₂)Li(THF)₂ (2). Metathesis with NaCp or LiCp* generates PcSc(η⁵-C₅H₅) and PcSc(η⁵-C₅Me₅), respectively, which represent the first examples of η⁵-Cp metal phthalocyanines where the Cp fragment sandwiches the metal centre.
