Abstract

The reduction in THF and oxidation in CH2Cl2 of the bent-sandwich complex (η5-lnd)2ZrMe2 (1) (Ind=C9H7, indenyl) were studied by cyclic voltammetry. Complex1 in THF undergoes one-electron reduction to radical anion1 −, which partially decomposes with the liberation of the Ind− anion. Even at −45°C the one-electron oxidation leads to the formation of an unstable 15-electron radical cation undergoing fast heterolytic decomposition to the Me• radical and (η5-lnd)2ZrMe2 cation, which is the key reaction center in the catalytic polymerization of olefins. Comparative analysis of electron-transfer-induced transformations of bent-sandwich dimethyl and dichloride zirconocenes of the general formula L2ZrX2 (L=η5-lnd, η5-Cp: X=Xl, Me) was performed.
