Electrochemical fluorination of trialkylphosphines
摘要:
The electrochemical fluorination (ECF) of trialkylphosphines results in the formation of the corresponding tris(perfluoroalkyl)difluorophosphoranes in good yield. In the case of ECF of tri(iso-butyl)phosphine, isomerisation of iso- into n-alkyl compound occurs. (C) 2000 Elsevier Science S.A. All rights reserved.

[P(C2F5)3F3]−, which is ideally suited for technical applications, functional substituents X are attached to the Lewis acid (C2F5)3PF2. In keeping with this, the reaction of (C2F5)3PF2 with 4-(dimethylamino)pyridine (DMAP) yields the corresponding adduct [P(C2F5)3F2(dmap)]. Treatment of this adduct with Brønsted acids (HX) leads to the selectiveformation of the corresponding phosphate anions [P(C2F5)3F2X]− by
弱配位阴离子(WCA)既具有学术意义,也具有工业价值。为了使理想地适合于技术应用的氟代磷酸烷基酯阴离子[P(C 2 F 5)3 F 3 ] -,官能取代基X连接至路易斯酸(C 2 F 5)3 PF 2。为此,(C 2 F 5)3 PF 2与4-(二甲基氨基)吡啶(DMAP)的反应产生相应的加合物[P(C 2 F 5)3 F 2(dmap)]。用布朗斯台德酸(HX)处理该加合物可通过用释放的碱DMAP俘获质子来选择性形成相应的磷酸根阴离子[P(C 2 F 5)3 F 2 X] -。通过这种方式,可以将OH功能一步转化为WCA,从而略微提高了相应阴离子的配位性能。与相应的[PPh 4 ]盐进行离子交换产生固体,而相应的咪唑鎓盐则作为室温离子液体获得。
