246047-72-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, cas is 246047-72-3,the ruthenium-catalysts compound, it is a common compound, a new synthetic route is introduced below.
To a solution of 6e (33.0 mg, 0.05 mmol) in anhydrous CH2Cl2 (6.0 ml) was added 2ndgeneration Grubbs catalyst (39.7 mg, 0.05 mmol) and CuCl (I) (4.6 mg, 0.05 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 2i (25.2 mg, 46%).Green crystals; mp 116.3-117.0 C; 1H NMR (270 MHz, CDCl3) delta 0.86 (d, J = 6.2 Hz,6H), 2.50 (br s, 18H), 4.23 (s, 4H), 4.45-4.54 (m, 1H), 7.07-7.12 (m, 6H), 7.26-7.54 (m,3H), 7.62 (d, J = 2.2 Hz, 1H), 7.80-7.87 (m, 4H), 16.51 (s, 1H); 19F (466 MHz, CDCl3)delta -80.6 (3F), 109.6 (2F), -121.1 (4F), -121.7 (4F), -122.5 (2F), -125.9 (2F); 13C NMR(68 MHz, CDCl3) delta 15.3, 22.1, 22.7, 66.0, 77.3, 110.3-119.9 (m, C8F17), 123.9, 124.3,124.7, 126.4, 127.3, 127.7, 127.9, 128.2, 129.1, 131.7, 132.8, 133.5, 133.7, 135.8, 136.3,155.8; IR (FT) 2919, 2360, 1605, 1481, 1398, 1242, 1207, 1145, 1109, 1094, 743 cm-1;HRMS (FAB) m/z [M+H]+ calcd for C49H44Cl2F17N2ORu 1172.1689; found 1172.1731.
The chemical industry reduces the impact on the environment during synthesis,246047-72-3,(1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium,I believe this compound will play a more active role in future production and life.
