Application | diiodo (parvaline) ruthenium (II) dimer is mainly used in asymmetric synthesis reactions, the intermediate [RuI2 p-isopropylbenzene] 2 can be prepared from [RuCI2 p-isopropylbenzene] 2 as a reaction raw material, and further iodinated to produce diiodine (parene) ruthenium (II) dimer. |
preparation | a) preparation of [RuI2 p-Cumene] 2: 2g of [RuCI2 p-Cumene] 2 and 50 ml of dichloromethane were placed in a flask under nitrogen. 66 mg of tetramethylammonium iodide followed by 10.2 mg of KI in water (50 ml) were added to the solution. The mixture was vigorously stirred at room temperature under inert gas for about 15 hours and the phases were separated. The aqueous phase was extracted with 2 × 40 ml of dichloromethane, the combined organic phases were washed with 3 × 40 ml of water, dried over sodium sulfate, and filtered over carlide. The red-brown solution was obtained and dried under vacuum to give 3.07g of [RuI2 p-isopropylphenyl] 2. B) preparation of diiodo (Paratan hydrocarbon) ruthenium (II) dimer: 155 mg of [RuI2-p-Cumene] 2 and 204 mg of () tmbp was placed in a flask under nitrogen and a mixture of 80 ml of dichloromethane and 30 ml of methanol degassed with nitrogen was added. The mixture was stirred under reflux for 1.5 hours, then it was cooled and concentrated under reduced pressure to give. |
