An efficient palladium-catalyzeddecarboxylative acylation of unactivated arenes with α-oxocarboxylic acids is reported. This method provides a novel access to aryl ketones.
An acylation of arenes with aldehydesthrough 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.
