5518-52-5 - Reference Information
| Application | Tris (2-furyl) phosphine is mainly used as phosphine ligand for organic synthesis of transition metal intervention, and is also used in Wittig reaction. It plays a wide range of roles in modern organic synthesis and practical applications. |
| preparation | replace the reaction flask with nitrogen atmosphere, add 20g of analytically pure furan, analytically pure TMEDA34.8 g and n-hexane 140mL to the reaction flask under mechanical stirring, drop 120mL of n-butyl lithium (analytically pure) with a concentration of 2.5M/L at room temperature, and after dropping, raise the temperature to 50 ℃ for 2 hours. 50mL of n-hexane solution of analytically pure PCl3 8g was added dropwise at 0 ℃. After the dropwise addition is completed, it was kept at this temperature for 1h, naturally raised to room temperature, and stirred for 5h. Pour the reaction liquid into 200mL of saturated ammonium nitrate aqueous solution, after full stirring, let it stand and layer to separate the organic phase, the aqueous phase is extracted with dichloromethane for 2-3 times, the organic phase is combined, and the organic phase is concentrated to obtain a crude product, The crude product is recrystallized with petroleum ether to obtain 11.1g of white crystal product three (2-furyl) phosphine, and the calculated yield is 82%, the purity of the product obtained by Agilent1100 liquid chromatograph is 99.1% |
