Visible-light promoted intermolecular halofunctionalization of alkenes with N-halogen saccharins

Abstract

We reported herein a simple and efficient visible-light promoted intermolecular haloamination and haloetherification of alkenes using N-halosaccharin as the halogen and nitrogen/oxygen source (halo = Br, Cl). The reaction can be applied to a very broad range of alkenes to generate haloamines and haloethers with high isolated yields. With DBU as the base, metal-free C–H amination of aryl olefins has also been achieved with good yields.
