Microreactor-Mediated Benzylic Bromination in Concentrated Solar Radiation

Abstract

Sunlight-induced bromination of benzylic compounds was conducted in a capillary microreactor, resulting in mono-brominated compounds with yields of up to 94 %. These reactions can be considered to be eco-friendly since they were carried out without an artificial light source or additional temperature control. In addition, up to 257.9 mmol could be produced daily using cost-effective molecular bromine, which leads to potential improvement of industrial processes.
