Reactions of [Zr(η-C5H5)2Cl 2] with LiR*(tmeda) [R* = CH(SiMe3)C 6H4Me-o, tmeda = Me2NCH2CH 2-NMe2] under different conditions yield [Zr(η-C 5H5)2(Cl)R*] (3), and the diastereoisomers meso - (2a) and rac - (2b) [Zr(η-C5H 5)2R*2], the latter of which is prepared from (2a) by photolysis or thermolysis; [Zr(η-C5H 5)2R*(thf)x] (x = 0-2) is obtained and characterised by e.s.r. spectroscopy in tetrahydrofuran (thf) solution by (a) Na[C 10H8]-thf-reduction of complex (2a), (2b), or (3) [via the radical anion of (3), itself accessible by reversible one-electron reduction of (3)], or (b) Na-Hg-thf-reduction of (3).
