Two-Step Continuous-Flow Synthesis of 6-Membered Cyclic Iodonium Salts via Anodic Oxidation

Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

A multi-step continuous-flow procedure for the generation of six-membered diaryliodonium salts was developed. This is a significant improvement of existing batch methods with regard to scalability and atom economy. The method uses easily accessible benzyl acetates in Friedel-Crafts-like alkylations while a subsequent anodic oxidative cyclization directly generates the corresponding cyclic iodonium salts.
