Integrative Photoreduction of CO₂ with Subsequent Carbonylation: Photocatalysis for Reductive Functionalization of CO₂

Abstract

Efficient conversion of CO₂ into fuels and chemicals with solar energy would be promising, but also faces great challenge. In this context, we describe the photoreductive functionalization of CO₂ to construct new C-C, C-N, and C-O bonds through the respective Pd-catalyzed Suzuki carbonylation, aminocarbonylation, and alkoxycarbonylation of aryl iodides with CO in situ generated through the photoreduction of CO₂ . This protocol opens up an alternative avenue for CO₂ utilization by harnessing solar energy.
