141556-45-8, 1,3-Dimesityl-1H-imidazol-3-ium chloride is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: Palladium (II) complex with 1-methylimidazole ligands[PdCl2(1-methylimidazole)2] (0.5 mmol, 0.17 g), K2CO3 (1.5 mmol,0.21 g), MgSO4 (0.2 g, for drying), an appropriate imidazoliumchloride (0.65 mmol) and finally a mixture of solvents CH3CN:THF(8 ml: 5 ml) were placed in a round-bottom flask equipped with astirring bar. The flask was capped with a rubber septum. Themixture was heated in the oil bath for 24 h at 50 C in the air atmosphere.During that time, the color changed from yellow togreenish. After the reaction, the cooled down mixture was filtratedto remove inorganic salts. Then, the yellow solutionwas evaporatedunder vacuum and the resulting oily residue was dissolved in aminimum amount of acetone. Next, 10 ml of water was slowlyadded to the yellow solution and clouding of the mixture wasobserved. The mixture was left to evaporate acetone and to enablesedimentation of the formed precipitate. After that time, waterwith excess of the imidazolium chloride and 1-methylimidazolewas decanted. The obtained product was washed with the waterand dried under vacuum. The complexes 2f and 2 g were obtainedfrom the appropriate imidazole and the precipitated solids requiredadditional washing with ethyl alcohol and diethyl ether. One of theobtained complexes [PdCl2(IMes)(1-methylimidazole)] (2e) wasdescribed in the literature [7b].
141556-45-8 1,3-Dimesityl-1H-imidazol-3-ium chloride 2734211, achiral-catalyst compound, is more and more widely used in various.
