| Abstract: | Abstract Reactions of the pyridyl side-chain-functionalized cyclopentadiene [C5H5CR2(CH2C5H4N)] [R 2 = Et2 (1), (CH2)4 (2)] with Ru3(CO)12 in refluxing xylene gave the new intramolecular C–H activated trinuclear product [μ-(C5H3N)CH2C(C2H5)2(C5H4)Ru(CO)]2Ru(CO)2 (3) and the normal dinuclear metal complex [(C5H4N)CH2C(CH2)4(C5H4)Ru(CO)]2(μ-CO)2 (4). The structures of the trinuclear complex 3 and dinuclear complex 4 were characterized by elemental analysis, IR spectra, 1H-NMR and X-ray diffraction. |
