Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, as a common heterocyclic compound, it belongs to ruthenium-catalysts compound, and cas is 246047-72-3, its synthesis route is as follows.

In a flame dry Schlenk tube 2nd generation Grubbs catalyst(98 mg, 0.11 mmol), CuCl (12.0 mg, 0.12 mmol) and ligand precursor 7 (35.0 mg, 0.11 mmol) were placed. Then, dry DCM was addedunder atmosphere of argon and a mixture was heated to 30 C. The progress of the reaction was monitored by TLC (c-Hex:EtOAc, 2:1).After 20 min the reaction mixture was cooled down to RT and thesolvent was evaporated. Purification by silica-gel chromatography(c-Hex:EtOAc, 10:1, followed by c-Hex:EtOAc, 3:2) yielded brick-redsolid (48%). A single crystal of compound 11 suitable for X-raydiffraction studies was grown at a temperature of 5 C from atrichloromethane/n-hexane solution. 1H NMR (400 MHz, CD2Cl2): delta= 17.9 (s, 1H, Ru]CHAr), 8.50 (d, 1H, J 12.0, Ar-H), 7.87 (dd, 1H,J 16.0, 8.0, Ar-H), 7.45-6.88 (m, 10H, Ar-H), 4.28-4.04 (m, 4H,CH2 2), 2.67-2.34 (br, 15H, CH3 5), 2.01 (s, 3H, CH3); 13C NMR(125 MHz, CD2Cl2): delta=303.9, 210.9, 142.8, 140.3, 136.8, 134.5, 132.7,130.5, 129.5, 128.7, 128.0, 125.7, 125.0, 123.0, 116.6, 77.5, 52.2, 51.1,20.9, 19.9, 19.8, 18.4, 17.6; IR (film from CH2Cl2): n 2913, 1607,1481, 1414,1258, 1013, 924, 849, 806, 763, 645, 576, 552 cm1; Anal.Calcd. for C34H36BrCl2N4ORu: C, 53.13; H, 4.72; N, 7.29; Found: C,53.81; H, 4.76; N, 7.27, m/z 791.0, [MNa].
