Carbonylative coupling of simple alkanes and alkenes enabled by organic photoredox catalysis

A visible-light-driven direct carbonylative coupling of simple alkanes and alkenes via the combination of a hydrogen atom transfer process and photoredox catalysis has been demonstrated. Employing the N -alkoxyazinium salt as the oxidant and the precursor of an oxygen radical, a variety of α,β-unsat...

Zusammenfassung:A visible-light-driven direct carbonylative coupling of simple alkanes and alkenes via the combination of a hydrogen atom transfer process and photoredox catalysis has been demonstrated. Employing the N -alkoxyazinium salt as the oxidant and the precursor of an oxygen radical, a variety of α,β-unsaturated ketones could be obtained in a metal-free fashion. A photoinduced metal-free three-component coupling of CO, alkanes and alkenes via the hydrogen atom transfer process has been developed. This protocol provides an efficient access to a range of valuable α,β-unsaturated ketones.
