Abstract: | A series of mononuclear ruthenium complexes RuCl(CO)(PMe3)3(CH CH-C6H4-R-p)] (R = H (2a), CH3 (2b), OCH3 (2c), NO2 (2d), NH2 (2e), NMe2 (2f)) has been prepared. The respective products have been characterized by elemental analyses, NMR spectrometry, and UV-Vis spectrophotometry. The structures of complexes 2c and 2d have been established by X-ray crystallography. Electrochemical studies have revealed that electron-releasing substituents facilitate monometallic ruthenium complex oxidation, and the substituent parameter values (σ) show a strong linear correlation with the anodic half-wave or oxidation peak potentials of the complexes. |
