新型含膦聚合前体4-溴-3-(二苯基膦酰基)-1-(1,2,2-三氟乙烯氧基)苯的合成

摘要

以间氨基苯甲醚为原料,经重氮化、溴化、Pd催化偶联、氧化、1,2-二溴四氟乙烷氟烷基化、Zn粉还原脱卤消除等反应制得合成全氟环丁基芳基醚聚合物的新型含膦聚合前体——4-溴-3-(二苯基膦酰基)-1-(1,2,2-三氟乙烯氧基)苯,其结构经NMR和MS表征.%A novel phenylphosphine oxide functionalized precursor for the synthesis of perfluorocy-clobutyl aromatic ether polymers, 4-bromo-3-diphenylphosphine oxide-l-( 1,2,2-trifluorovinyloxy) benzene, was synthesized from m-anisidine by diazotization, bromination, Pd-catalyzed coupling, oxidation, fluoroalkylation, Zn reductive dehalogenation and so on. The structure was characterized by NMR and MS.
