A mixture of [RuCl2(COD)]n (155 mg, 0.552 mmol) and la (147 mg, 0.552 mmol) was stirred in toluene (10 ml) at 115 C for 48 h in Kontes pressure tube. After cooling, a brick-colored precipitate was collected on a filter frit, washed with Et20 (3 x 10 ml) and vacuum dried on the filter. The material was extracted on the filter with 5 x 3 ml CH2C12 allowing the filtrates to be collected in 5 separate vials. A red solution in each vial was layered with Et20 (20 ml). In 1 week, the combined precipitates (or red crystals) from each vial were collected, washed with Et20 (3 x 10 ml) and vacuum-dried to afford 144 mg of the desired product (60%). Elem. Anal: Calcd for C28H44CI4N4O2RU2S2 (876.75): C, 38.36; H, 5.06; N, 6.39%. Found C, 38.38; H, 4.99; N, 6.32%. Elem. Anal: Calcd for C28H44CI4N4O2RU2S2 (876.75): C, 38.36; H, 5.06; N, 6.39%. Found (under nitrogen): C, 38.61; H, 4.99; N, 6.17%. The complex is poorly soluble in CDC13, slightly better in CD2C12. 1H NMR (400 MHz, CD2C12, r.t., saturated): delta 2.00 (brs, 1H), 2.15 (d, J~ 14 Hz, 1H), 2.37 (t, J~ 12 Hz, 1H), 2.15 (m, 4H), 2.75-2.94 (m, 3H), 3.04 (d, J~ 14 Hz, 1H), 3.07-3.23 (m, 5H), 3.38 (m, 2H), 3.44-3.62 (m, 3H), 3.61-3.75 (m, 3H), 3.79 (d, J~ 12 Hz, 1H), 3.87 (t, J~ 14 Hz, 1H), 3.93-4.09 (overlapped m, 3H), 4.06 (brs, 1H), 4.44 (t, J~ 11 Hz, 1H), 4.72 (brs, 1H, possibly NH), 5.07 (d, J~ 18 Hz, 1H), 6.72-8.85 (overlapped, 10H), 9.19 (brs, 1H, NH – C1). The same compound is obtained if the synthesis is carried out in the presence of P(C6F5)3. (0457) [0216] An X-ray structure of complex K-1 revealed that one ligand coordinates to one Ru atom via mer-fashion. A second ligand coordinates to second Ru atom via ^ac-fashion. Both Ru atoms are connected via one bridging CI atom. One S(Ph) atom is part of mer-coordinated la. There appears to be a hydrogen-bonding interaction between one NH group of the fac- coordinated ligand and terminal CI atom attached to the first Ru atom. Complex K-1 exists as a single species in solution. The NH hydrogen atom H-bonded to the chloride ligand appears at delta 9.19 ppm in the 1H NMR spectrum. It is shifted to low field by Deltadelta = 4.47 ppm relative to the NH resonance of the non-H bonded NH group.
