Abstract
A monosubstituted decarbonylation reaction was performed on cis-, cis-[Ru(η2-N(O)C10H6O)2(CO)2] (cis-NO, cis-O) (A), trans-, cis-[Ru(η2-N(O)C10H6O)2(CO)2] (trans-NO, cis-O) (B), cis-, cis-[Ru(η2-OC10H6N(O))2(CO)2] (C), trans-, cis-[Ru(η2-OC10H6N(O))2(CO)2] (D) and cis-, trans-[Ru(η2-OC10H6N(O))2(CO)2] (cis-NO, trans-O) (E) with donor ligand (L) 4-phenylpyridine (ppy), 4-(2-(9-anthryl)vinyl)pyridine (avpy) or triphenylphosphine (PPh3) to give substituted complex cis-, cis-[Ru(η2-N(O)C10H6O)2(CO)L] (1a, L = ppy; 2a, L = avpy; 3a, L = PPh3), trans-, cis-[Ru(η2-N(O)C10H6O)2(CO)L] (1b, L = ppy), cis-, cis-[Ru(η2-OC10H6N(O))2(CO)L] (1c, L = ppy; 2c, L = avpy), trans-, cis-[Ru(η2-OC10H6N(O))2(CO)L] (1d, L = ppy; 2d L = avpy) or cis-, trans-[Ru(η2-OC10H6N(O))2(CO)L] (1e, L = ppy). Progressive substitution of the carbonyl ligands of A by tributylphosphine (PBu3) or functionalized pyridine 4-formylpyridine (fpy), 4-ethylpyridine (epy)or 4-dimethylaminopyridine (mapy) gave a centrosymmetric bisubstituted complex trans-, trans-[Ru(η2-N(O)C10H6O)2L2] (8a, L = PBu3; 9a, L = fpy; 10a, L = epy; 11a, L = mapy) together with the corresponding mono-CO-substituted complex cis-, cis-[Ru(η2-N(O)C10H6O)2(CO)L] (4a, L = PBu3; 5a, L = fpy; 6a, L = epy; 7a, L = mapy). The electronic absorption spectra and metal-localized oxidation formal potentials changed significantly for the bisubstituted complexes compared with the monosubstituted ones.
