As a common heterocyclic compound, it belongs to chiral-catalyst compound, name is 1,3-Dimesityl-1H-imidazol-3-ium chloride, and cas is 141556-45-8, its synthesis route is as follows.
A butterfly for the keto-carbonyl of bridge [2Fe2Se] kind of iron-iron hydrogenase models object 5 preparation method, the chemical formula of the model [( mu-SeCH 2 (CO) CH 2 Se-mu)] Fe 2 (CO) 5 (IMes) (IMes=1,3-b (2, 4, 6-trimethyl phenyl) imidazole-2-carbene), shown in the preparing process is as follows. Specific preparation steps are as follows: 1) in high purity under the protection of nitrogen, with stirring to the drying of the magneton 100 ml reaction flask by adding 455 mg (1.336mmol) 1,3-bis (2, 4, 6-trimethyl phenyl) imidazole hydrochloride and 20 ml tetrahydrofuran, shall be mixed solution; 2) in the above-mentioned mixed solution is added with 1.6Mn-BuLi solution 1 ml, stirring the mixture at room temperature for 20 min, the reaction liquid obtained, the above-mentioned reaction solution is then filtered, and the filtrate by adding in 165 mg (0.334mmol) 1 further reaction to obtain a reaction mixture; 3) the above-mentioned reaction mixture, the solvent is pumped under reduced pressure, the residue is extracted with methylene chloride, the volume ratio of 1:1 mixture of dichloromethane-petroleum ether as a developing agent thin layer chromatographic separation, collection red the main ribbon, obtain a red solid 159 mg, the chemical formula is [( mu-SeCH 2 (CO) CH 2 Se-mu)] Fe 2 (CO) 5 (IMes) (5), the yield is 62%.
141556-45-8, 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.,141556-45-8 ,1,3-Dimesityl-1H-imidazol-3-ium chloride, other downstream synthetic routes, hurry up and to see
