An acylation of arenes with aldehydes
through dual C–H activations
at room temperature is reported. The acylation was initiated by phenanthraquinone-catalyzed
hydrogen atom transfer from aldehyde under visible light irradiation.
The aldehyde-derived acyl radical merged with palladium-catalyzed
activation of arenes to afford the cross coupling products.
