Metallophthalocyanin-ocenes: scandium phthalocyanines with an η(5)-bound Cp ring.
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(η(5)-C5H5) and PcSc(η(5)-C5Me5), respectively, which represent the first examples of η(5)-Cp metal phthalocyanines where the Cp fragment sandwiches the metal centre.
