321921-71-5 - Reference Information
| Use | n-butyldi (1-adamantyl) phosphine is a catalyst. n-butyl di (1-adamantyl) phosphine is an electron-rich phosphine ligand used in palladium-catalyzed cross-coupling reactions such as Heck and Suzuki coupling reactions. |
| Application | n-butyl di (1-adamantyl) phosphine is a novel phosphine ligand, which can be made of di (1-adamantyl) phosphine and di-n-butyl ether in one step to prepare hi is obtained. Although palladium (0)/nickel (0) compounds are known as present reaction catalysts, palladium and nickel catalysts for activating and refining halogenated aromatic compounds with are palladium (II) and/or nickel (II) and palladium (0) and/or nickel (0) complexes. |
| preparation | 4.6g(15mmol) di (1-adamantyl) phosphine was placed in 50ml di-n-butyl ether and 20ml of 2.5Mn-BuLi(50mmol) toluene solution was added. The solution was refluxed for 1 hour and cooled, and 2.8g(30mmol) of 1-butyl chloride was added dropwise. The mixture was refluxed for 30 minutes, cooled and washed with a saturated ammonium chloride solution (3x), the organic phase was separated and dried on sodium sulfate and the solvent was distilled off under reduced pressure. The product was purified by spherical tube distillation under high vacuum. Yield: 4.6g(13mmol,85%) n-butyl di (1-adamantyl) phosphine. |
