With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.246047-72-3,(1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium,as a common compound, the synthetic route is as follows.
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.
246047-72-3, The synthetic route of 246047-72-3 has been constantly updated, and we look forward to future research findings.
