Abstract

Reaction of [M(η-C₅H₅)₂Cl₂] (M = T1, Zr, or Ht) with o-C₆H₄[CH(SiMe ₃)L1(tmeda)]₂ (tmeda = Me₂NCH ₂-CH₂NMe₂) in OEt₂ is stereospecific, generating the meso-metallocycle [M{CH(SiMe₃)C ₆H₄CH(SiMe₃)-o}(η-C₅H ₅)₂], (1), in high yield, cyclic voltammetry of complexes (1) in tetrahydrofuran shows a reversible one-electron reduction (-E _1/2 ^red Hf > Zr > > Ti) to yield relatively persistent M^III anions (t_1/2 > 10 s) characterised by their e s r spectra.
