Synthesis and structure of a chelating arene–ruthenium complex [RuCl2(PPh2(CH2)3-η6-C6H5)]
摘要:
The synthesis of an arene-phosphine ligand, Ph2P(CH2)(3)Ph, has provided a route into a new chelating arene-phosphine-ruthenium complex, [RuCl2(PPh2(CH2)(3)-eta(6)-C6H5)] which has been structurally characterized. This complex can be made by thermolysis of [(eta(6)-MeC6H4CHMe2)RuCl2(PPh2(CH2)(3)Ph)] or electrochemically utilizing the formation of the labile seventeen-electron ruthenium(III) species [(eta(6)-MeC6H4CHMe2)RuCl2(PPh2(CH2)(3)Ph)](+) which can be converted in good yield into [RuCl2(PPh2(CH2)(3)-eta(6)-C6H5)].

Tethered arene-ruthenium complexes [RuCl2eta (1):eta (6)-Me2P(CH2)(3)C6H5}], [RuCl2eta (1):eta (6)-Ph2PCH2SiMe2C6H5}] and [RuCl2eta (1):eta (6)-Ph2P(CH2)(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(eta (6)-1,2-MeC6H4CO2Me)](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 Ag / AgCl and decrease with increasing methyl substitution on the arene.
