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.,246047-72-3
To a solution of 6a (45.0 mg, 0.07 mmol) in anhydrous CH2Cl2 (6.0 ml) was added 2ndgeneration Grubbs catalyst (53.4 mg, 0.06 mmol) and CuCl (I) (13.9 mg, 0.14 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 2e (28.9mg, 37%).Green crystals; mp 135-137 C (dec.); 1H NMR (270 MHz, CDCl3) delta 1.21 (d, J = 6.2Hz, 10H), 2.38-2.47 (m, 18H), 3.79 (s, 3H), 4.20 (s, 4H), 5.80-5.75 (m, 1H), 6.73 (s,1H), 7.06 (s, 4H), 16.32 (s, 1H); 19F NMR (466 MHz, CDCl3) delta -80.6 (3F) -109.9 (2F),-121.1 (4F), -121.7 (4F), -122.5 (2F), -125.9 (2F); 13C NMR (68 MHz, CDCl3) delta 21.9,22.5, 26.1, 26.4, 29.7, 30.3, 51.4, 56.0, 75.9, 76.2, 109.3, 116.8, 122.8, 123.8, 126.6,127.6, 128.7, 132.8, 137.3, 139.1, 147.1, 149.6, 209.6, 295.0; IR (FT) 3853, 3737, 3638,2935, 2856, 2363, 2326, 1581, 1455, 1187, 1104, 898, 747 cm-1; HRMS (FAB) m/z[M+H]+ calcd for C40H40Cl2F17N2O2Ru 1076.1239; found 1076.1250.
With the complex challenges of chemical substances, we look forward to future research findings about (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium
