(1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, cas is 246047-72-3, it is a common heterocyclic compound, the ruthenium-catalysts compound, its synthesis route is as follows.,246047-72-3
To a solution of 13b (40.0 mg, 0.065 mmol) in anhydrous CH2Cl2 (6.0 ml) was added2nd generation Grubbs catalyst (50.3 mg, 0.059 mmol) and CuCl (I) (13.0 mg, 0.13mmol) under nitrogen at 30 C and stirred for 3 h. The reaction mixture was concentrated in vacuo, and the residue was purified by column chromatography onsilica gel (hexane / AcOEt = 2 / 1) to give 3b (55.5 mg, 78%).green crystals; mp 160-165 C (dec.); 1H NMR (270 MHz, CDCl3) delta 2.01-2.04 (m, 2H),2.22-2.31 (m, 2H), 2.43 (d, J = 14.8 Hz, 18H), 2.77-2.87 (m, 4H), 4.10-4.21 (m, 6H),6.51 (s, 1H), 7.08 (s, 5H), 16.43 (s, 1H); 19F NMR (466 MHz, CDCl3) delta -80.5 (3F),-114.4 (2F), -121.5 (2F), -121.8 (4F), -122.5 (2F), -123.3 (2F), -126.0 (2F); 13C NMR(68 MHz, CDCl3) delta 19.2, 21.0, 22.5, 23.5, 51.7, 69.5, 77.5, 118.9, 124.1, 128.9, 129.5,133.2, 136.3, 138.7, 143.7, 148.5, 210.7, 291.4; IR (FT) 3905, 3857, 3816, 3743, 3700,3642, 3616, 3569, 3013, 2945, 2913, 2856, 2363, 2331, 1738, 1691, 1596, 1555, 1476,1455, 1413, 1245, 1203, 1140, 1108, 1035, 993, 915, 857, 814, 730 cm-1; HRMS (FAB)m/z [M+H]+ calcd for C41H40Cl2F17N2ORu 1072.1290, found 1072.1320.
With the rapid development of chemical substances, we look forward to future research findings about 246047-72-3
