It is a common heterocyclic compound, the ruthenium-catalysts compound, (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, cas is 246047-72-3 its synthesis route is as follows.
To a solution of 9 (59.7 mg, 0.098 mmol) in anhydrous CH2Cl2 (6.0 ml) was added 2ndgeneration Grubbs catalyst (75.3 mg, 0.088 mmol) and CuCl (I) (19.8 mg, 0.20 mmol)under nitrogen at 30 C and stirred for 3 h. The reaction mixture was concentrated invacuo, and the residue was purified by column chromatography on silica gel (hexane /CH2Cl2 = 1 / 1) to give 2j (43.2 mg, 41%).Green crystals; mp 153-157 C; 1H NMR (270 MHz, CDCl3) delta 2.38 (s, 6H), 2.45 (s,12H), 4.21 (s, 1H), 4.90-4.82 (m, 1H), 6.62 (d, J = 12.4 Hz, 1H), 7.07 (s, 5H), 16.22 (s,1H); 19F NMR (466 MHz, CDCl3) delta -80.6 (3F), -106.3 (1F), -108.5 (2F), -121.4 (2F),-121.5 (2F), -122.6 (4F), -125.9 (2F); 13C NMR (68 MHz, CDCl3) delta 19.4, 20.9, 51.4,77.5, 102.8, 103.2, 122.3, 129.4, 139.1, 141.8, 155.8, 155.9, 158.3, 162.1, 209.2, 291.7;IR (FT) 3905, 3857, 3747, 3642, 3569, 2971, 2918, 2363, 2342, 1837, 1723, 1691, 1612,1586, 1486, 1424, 1293, 1213, 1156, 1104, 1029, 915, 846 cm-1; HRMS (FAB) m/z[M+H]+ calcd for C39H37Cl2F18N2ORu 1064.1039; found 1064.1049.
