246047-72-3, (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium is a ruthenium-catalysts compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of 13a (22.0 mg, 0.038 mmol) in anhydrous CH2Cl2 (5.0 ml) was added2nd generation Grubbs catalyst (29.0 mg, 0.034 mmol) and CuCl (I) (7.5 mg, 0.075mmol) under nitrogen at 30 C and stirred for 3 h. The reaction mixture wasconcentrated in vacuo, and the residue was purified by column chromatography onsilica gel (hexane / CH2Cl2 = 1 / 1) to give 3a (14.0 mg, 35%).Green crystals; mp 178-183 C (dec.); 1H NMR (270 MHz, CDCl3) delta 2.09-2.00 (m, 2H),2.43 (d, J = 14.0 Hz, 18H), 2.86 (t, J = 12.1 Hz, 2H), 4.17 (s, 4H), 4.27 (t, J = 10.2 Hz,2H), 6.91 (s, 1H), 7.08 (s, 4H), 7.43 (s, 1H), 16.32 (s, 1H); 19F NMR (466 MHz, CDCl3)delta -80.5 (3F), -109.2 (2F), -121.0 (2F), -121.3 (2F), -121.7 (4F), -122.5 (2F), -126.0(2F); 13C NMR (68 MHz, CDCl3) delta 19.2, 21.0, 22.1, 23.6, 51.7, 70.2, 118.0, 123.3,124.2, 127.1, 129.6, 136.1, 138.7, 139.0, 142.8, 143.2, 151.8, 209.2, 288.5; IR (FT)3979, 3857, 3747, 3685, 3417, 2956, 2918, 2363, 2336, 1596, 1481, 1413, 1240, 1208,1140, 1046, 988, 904, 857, 809, 741, 720 cm-1; HRMS (FAB) m/z [M+H]+ calcd forC39H36Cl2F17N2ORu 1044.0977; found 1044.0991.
