Oxidation-Induced Rearrangement from a <i>nido</i>- to a <i>closo</i>-Ruthenacyclopentadiene
journal contribution
posted on 2006-11-06, 00:00 authored by Toshiro Takao, Akiko Inagaki, Tsubomi Imamura, Hiroharu SuzukiTwo-electron oxidation of a triruthenium <i>nido</i>-ruthenacyclopentadiene complex, {Cp*Ru(μ-H)}<sub>3</sub>(CMeCR−CHCH) (<b>1a</b>; R = H, <b>1b</b>; R = Me, Cp* = η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>), proceeds
at −78 °C and exclusively affords a cationic <i>closo</i>-ruthenacyclopentadiene complex, [(Cp*Ru)<sub>2</sub>{Cp*Ru(CHCMe−CRCH)}(μ-H)<sub>2</sub>](PF<sub>6</sub>) (<b>6a</b>; R = H, <b>6b</b>; R = Me).
