Neutrally photoinduced MgCl2-catalyzed alkenylation and imidoylation of alkanes

Abstract

We report a practical protocol for the oxidation of the chloride ion (Cl) to the chlorine radical (Cl˙) via photoinduced MgCl2 catalysis, avoiding the use of strong acids, formal oxidants, and photocatalysts. Visible light plays a crucial role in enabling the Cl radical formation from Cl through electron transfer. The thus formed reactive chlorine radical facilitates hydrogen atom abstraction of light alkanes and enables efficient alkenylation and imidoylation with organic sulfones under redox-neutral and acid-free conditions. The use of readily available alkanes and a broad substrate scope make this strategy attractive for the construction of value-added chemicals.
