In this study we use in situ infrared tracking to describe the kinetics of dual photo- and nickel-catalyzed carboxylate O-arylations. We examined both a state-of-the-art homogeneous (Ir(ppy)<sub>3</sub>) and heterogeneous (graphitic carbon nitride) photocatalyst, comparing their kinetics to each other, and to the existing mechanistic proposal. We argue against the current hypothesis, specifically that the photocatalyst is only involved to trigger a rate-limiting reductive elimination.<br>

Graphitic Carbon Nitride

Here we propose the emulsification of CO2 and water with graphitic carbon nitride (g-C3N4), in which the g-C3N4-stabilized CO2 droplets were utilized as “microreactors” for in situ photocatalytic CO2 reduction.
