Abstract:
We describe a multi-step continuous-flow procedure for the generation of six-membered diaryliodonium salts. The accompanying scalability and atom economy are significant improvements to existing batch methods. Benzyl acetates are submitted to this two-step procedure as highly available and cheap starting materials. An acid-catalyzed Friedel-Crafts alkylation followed by an anodic oxidative cyclization yielded a defined set of cyclic iodonium salts in a highly substrate-dependent yield.
摘要:
我们描述了一种用于生成六元二芳基碘鎓盐的多步骤连续流程序。伴随的可扩展性和原子经济性是对现有批处理方法的重大改进。将乙酸苄酯作为高度可用且廉价的起始材料进行该两步程序。酸催化的Friedel-Crafts烷基化,然后进行阳极氧化环化,以高度依赖底物的产率产生了一组确定的环状碘鎓盐。
