Name is Dichloro(2-isopropoxyphenylmethylene)(tricyclohexylphosphine)ruthenium (II), as a common heterocyclic compound, it belongs to ruthenium-catalysts compound, and cas is 203714-71-0, its synthesis route is as follows.
In a glove box, NHC ligand precursor 23 (63 mg, .13, mmol), ruthenium precursor 11 (78 mg, .13 mmol) and KOMJu(Fe) (29 mg, .13 mmol) were combined in toluene. The flask was sealed, removed from the glove box and stirred at 60 0C for 18 hours. The reaction was concentrated and purified by flash column chromatography (5% –> 20% Et2O/Pent). There were 3 bands that could be isolated from this column, first 2 brown bands and then one green band. The second brown band was the desired product; however, it was not completely pure after one column. Recolumning in 10% Et2O/Pentane gave a brown oil product completely pure by 1H NMR (9 mg, 9%) and another fraction still slightly impure (18 mg, 18%). The products were lyophilized from benzene to give solids. 1H NMR (300 MHz, CDCl3) delta 16.78 (s, IH), 8.13 (br, 2H), 7.74-7.62 (m, 4H), 7.07-7.04 (m, IH), 6.97 (dd, J = 3, 1.5 Hz, IH), 6.66 (t, J = 7.5 Hz, 3H), 6.34 (d, J = 8.4 Hz, IH), 4.49 (sept, J = 6 Hz, IH), 1..44 (d, J = 6 Hz, 6H), 1.44 (br, 18H), 1.18 (br, 18H); 13C (75 MHz, CDCl3) delta; HRMS (EI+) calc for C4IH56Cl2N2ORu, 764.2814. Found 764.2842.
203714-71-0, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,203714-71-0 ,Dichloro(2-isopropoxyphenylmethylene)(tricyclohexylphosphine)ruthenium (II), other downstream synthetic routes, hurry up and to see
