with phosphorus(III) halides was explored. In the process a new convenient, one-pot, high yield method for the synthesis of (perfluoroalkyl)phosphonic acids has been developed. Perfluoroalkyl Grignard reagents react with phosphorustrichloride or phosphorus tribromide to form (perfluoroalkyl)phosphonous dihalides. Hydrolysis gives the corresponding (perfluoroalkyl)phosphonous acids. Oxidation of the
探索了全氟烷基格氏试剂与卤化磷(III)的反应。在该方法中,已经开发了一种新的方便,一锅法,高收率的合成(全氟烷基)膦酸的方法。全氟烷基格氏试剂与三氯化磷或三溴化磷反应生成(全氟烷基)二卤化磷。水解得到相应的(全氟烷基)亚膦酸。基于相应的全氟烷基碘,用H 2 O 2氧化亚膦酸可产生60-78%的总产率的(全氟烷基)膦酸。甲苯鎓盐[MeC 6 H 4 NH 3 ] 2 [C 2报道了F 5 PO 3和[MeC 6 H 4 NH 3 ] [C 8 F 17 P(O)2 OH]。
