Visible light-induced recyclable porous g-C3N4 promoted one-pot alcohol oxidation–Wittig tandem reactions

Recyclable g-C 3 N 4 catalyzed one-pot alcohol oxidation–Wittig tandem reactions were realized under the irradiation of blue LEDs and various α,β-unsaturated esters were facilely synthesized in good to excellent yields and moderate to good E / Z ratios.
