Carbon Nitride Photoredox Catalysis Enables the Generation of the Dioxolanyl Radical for Conjugate Addition Reactions

Abstract

Graphitic carbon nitride (g-C3N4) is used as photocatalyst in the Giese reaction of dioxolane and a wide variety of electron-deficient olefins. The catalyst is shown to be reusable over five cycles with no changes in catalyst composition, morphology, and characteristics observed by scanning electron microscopy, elemental analysis, infrared spectroscopy, and powder X-ray diffraction.
