Description
技术领域
本发明属于有机化合物的制备技术领域,具体涉及一种芳甲基膦酰化物的制备方法。
背景技术
取代二苯乙烯(1)广泛存在于天然产物结构中,此外广泛应用于合成染料、荧光剂、增白剂等领域。PPVs(2)是一种重要的聚合物,它被广泛应用于发光二极管及其他光伏器件的制作中(参见文献1.Thomas Junkers, Joke Vandenbergh, Peter Adriaensens,Laurence Lutsenb, Dirk Vanderzande. Polym. Chem.2012, 3, 275–285. 2. TaoShen, Xiao-Ning Wang, Hong-Xiang Lou. Nat. Prod. Rep.2009, 26, 916–935. 3.Frank B. Mallory., Clelia W . Mallory. Organic Reaciton. 1984, 30, 1-456. 4.Andrew C.

Rev., 2007, 107, 1324–1338. 6.Tian-Zeng Huang, Tie-Qiao Chen, Li-Biao Han. J. Org. Chem. 2018, 83, 2959-2965)。
芳甲基膦酰化物可以方便地转化为取代二苯乙烯(文献6. Tian-Zeng Huang,Tie-Qiao Chen, Li-Biao Han. J. Org. Chem. 2018, 83, 2959-2965);它也可以通过简单的步骤合成PPVs(2))(参见文献4. Andrew C. Grimsdale, Khai Leok Chan, RainerE. Martin, Pawel G. Jokisz, Andrew B. Holmes. Chem. Rev.2009, 109, 897–1091.)。
此外,芳甲基磷酸酯可以在氧气和碱的存在下,室温转化为酮。其中,二苯甲酮(3)是一种用途广泛的化工原料;近年来,二苯甲酮作为光催化剂,成功应用于多种光催化反应中(参考文献:7. Chandra Bhushan Tripathi, Tsuyoshi Ohtani, Michael T.Corbetta, Takashi Ooi. Chem. Sci., 2017, 8, 5622-5627. 8. Subhasis Paul,Joyram Guin. Green. Chem., 2017, 19, 2530-2534. 9. Yuuki Amaoka, MasanoriNagatomo, Mizuki Watanabe, Keisuke Tao, Shin Kamijo, Masayuki Inoue.Chem. Sci., 2014, 5, 4339–4345. 10.

已公开的芳甲基膦酰化物的合成主要有以下方法:
一、以取代溴化苄或氯化苄、二芳基氧磷为原料,在强碱作用下反应得到相应的产物,该方法需要使用具有强刺激性的苄溴或苄氯,对人体和环境危害大。
二、以取代苄醇或苯甲醛、二芳基氯化膦为原料,在碘离子作用下制备相应的芳甲基膦酰化物,该方法需要使用二芳基氯化膦,该原料毒性较大、不够稳定、易吸湿分解。此外,反应需要在无水条件下进行。
三、以取代苄醇和二芳基乙氧基磷酯为原料,在碘离子作用下制备相应的芳甲基膦酰化物,该方法需要使用二芳基乙氧基膦为原料,该物质为非普通原料,容易被空气氧化,不易储存。
以上公开的方法中存在着各种缺陷,因此开发原料来源方便、反应条件温和、操作简便、普适性好的制备芳甲基膦酰化物的合成方法非常重要。
