Visible-light Photoredox Catalyzed Pinacol coupling in Water

Abstract

We developed the visible-light mediated photoredox-catalyzed Pinacol coupling in water. This reaction is eco-friendly and economical because it uses water as a solvent and 4CzIPN, an organic photocatalyst that is cheap and easy to make. Various functional groups were tolerated under mild and metal-free conditions to provide good to excellent yields
