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
Example 1Synthesis of Ru complex 4a (H2IMes)(PCy3)Cl2Ru=CHPh (formula lb, 860mg, l .Ommol) and CuCl (270 mg, 2.5mmol, 2.5 eq) were added into a 100 mL of two-neck round-bottom flask filled with inert gas (Ar), and followed by adding DCM (15 mL) and ligand 3a (250 mg, 1.2mmol, 1.2 eq) into the DCM solution at 20-25C. The reaction was stirred until completed in 30-60 min. (monitored by TLC). The reaction mixture was filtered and concentrated, then purified by flash column eluting with a gradient solvent (Pentane/DCM 2/1 to DCM). The purified solid product was washed with methanol, and dried under vacuum to obtain 27mg of green solid product 4a, yield: 4%. The green product was confirmed by 1HNMR. Ru complex (4a) 1HNMR (400 MHz, CDC13): delta 19.09 (s, lH, Ru=CH),7.51-6.70 (m, 13H), 5.31 (m, 1H), 4.30 (d, J = 12.9 Hz, 1H), 4.04 (s, 4H, NCH2CH2N), 3.61 (d, J= 12.9 Hz, 1H), 2.45 (s, 12H), 2.33 (s, 6H).; Example 9 Synthesis of Ru complex 4j The synthetic procedure is the same as in Example 1 in 1.0 mmol scale. 353 mg of green solid product 4j was obtained (yield: 48%). Ru complex (4j) 1H- MR (400 MHz, CDC13): delta 18.88 (s, lH, Ru=CH), 7.57-6.44 (m, 11H), 5.36 (t, J = 13.2 Hz, 1H), 4.16-4.02 (m, 5H), 4.01 (d, J = 13.2 Hz, 1H), 2.75-2.00 (m, 19H), 1.01-0.90 (m, 6H)., 246047-72-3
As the paragraph descriping shows that 246047-72-3 is playing an increasingly important role.
