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 MIII anions (t1/2 > 10 s) characterised by their e s r spectra.
