Advances in the field of phosphorus chemistry are documented, by revealing the synthetic utility of previously underutilized quaternary phosphiranium salts (QPrS) as three‐chain‐atom electrophilic building blocks. Notably, control of their challenging C‐centered electrophilicity is disclosed with an expedient synthesis of tertiary β‐anilino phosphines as a proof‐of‐concept.
We report the preparation of phosphiranium salts by quaternarization of phosphiranes, a class of sensitive, highlystrained, and poorly nucleophilic cyclic phosphines. High-yielding introduction of a varied set of alkyl groups including methylene ester arms was accomplished under mild conditions. A Cu-catalyzed electrophilic arylation of phosphiranes using diaryl iodonium reagents was also achieved
我们报告了通过 phosphiranes 季铵化制备 phosphiranium 盐,这是一类敏感的、高度紧张的、亲核性差的环膦。在温和条件下实现了包括亚甲基酯臂在内的一系列不同烷基的高产率引入。还实现了使用二芳基碘鎓试剂对磷烷进行 Cu 催化的亲电芳基化,以产生前所未有的 P,P-二芳基磷鎓盐,并具有良好的效率。
