250285-32-6, 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(2,6-diisopropylphenyl)imidazolium chloride, cas is 250285-32-6,the chiral-catalyst compound, it is a common compound, a new synthetic route is introduced below.
Under the protection of nitrogen, to the reaction tube is sequentially added imidazole salt IPr¡¤HCl (1.1mmol), palladium chloride (1.0mmol), potassium carbonate (2.2mmol), tetrahydrofuran (5.0 ml) and isoquinoline (2.0mmol). The mixture is placed in the oil bath heated reaction (80 C) 12 hours. Stopping the reaction, cooling to room temperature, pressure reducing turns on lathe does solvent, rapid column chromatography separation to obtain a yellow solid product 0.1148g, yield 83%.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride, 250285-32-6
