deoxyfluorination of carboxylic, sulfonic, phosphinic acids and phosphine oxides is a fundamentally important approach to access acyl fluorides, sulfonyl fluorides and phosphoric fluorides, thus the development of inexpensive, stable, easy‐to‐handle, versatile, and efficient deoxyfluorination reagents is highly desired. Herein, we report the use of potassium salts of perfluoroalkyl ether carboxylic acids (PFECA)
羧酸,磺酸,次膦酸和氧化膦的脱氧氟化是获取酰基氟,磺酰氟和氟化磷的根本重要方法,因此,开发廉价,稳定,易于操作,通用和有效的脱氧试剂非常重要想要的。本文中,我们报告了使用具有CF 2 O单元的全氟烷基醚羧酸(PFECA)的钾盐作为脱氧氟化剂,这在制造六氟丙烯氧化物(HFPO)时主要是作为副产物而产生的。酰氟,磺酰氟和磷酰氟的合成可以通过原位生成的二氟化碳(COF 2)实现 PFECA盐的热降解所致。
