| titleOfInvention | Preparation method of alkenyl diphenylphosphine compound |
| abstract | The invention discloses a preparation method of an alkenyl diphenylphosphine compound. The method takes aryl ethylene derivatives and diphenyl phosphorus oxide as initial raw materials, cerium ammonium nitrate is added simultaneously under the protection of nitrogen, and the proportions of the aryl ethylene derivatives, the diphenyl phosphorus oxide and the cerium ammonium nitrate are calculated according to the molar ratio1 (2-3) and (1-3), adding an organic solvent to a solution concentration of 0.2 mol/L (relative to diphenylphosphine oxide), and then, prior to the reaction temperature of 40 o C, reacting for 6 hours, and then heating to 90 DEG C o C, reacting for 12 hours until the reaction is finished, then removing the solvent by rotary evaporation, and carrying out column chromatography to obtain the alkenyl diphenylphosphine compound. The method has the advantages of simple reaction system, easily obtained starting raw materials, convenient operation and wider substrate applicability. |
