Abstract

Tethered arene-ruthenium complexes [RuCl₂{η¹:η⁶-Me₂P(CH ₂)₃C₆H₅}], [RuCl₂{η¹:η⁶-Ph₂PCH ₂SiMe₂C₆H₅}] and [RuCl₂{η¹:η⁶-Ph₂P(CH ₂)₃(aryl)}] (aryl=2,4,6-C₆H₂Me₃, C₆Me₅) have been prepared by thermal displacement of methyl o-toluate from the appropriate P-donor derivatives of [RuCl₂(η⁶-1,2-MeC₆H₄CO ₂Me)]₂ and their structures determined by X-ray studies. The tethered complexes undergo reversible one-electron oxidation by cyclic voltammetry; the half-wave potentials are in the range 1.10-1.34 V versus AgAgCl and decrease with increasing methyl substitution on the arene.
