title: Room-Temperature Decarboxylative Couplings of α-Oxocarboxylates with Aryl Halides by Merging Photoredox with Palladium Catalysis.
abstract: Enabled by merging iridium photoredox catalysis and palladium catalysis, α-oxocarboxylate salts can be decarboxylatively coupled with aryl halides to generate aromatic ketones and amides at room temperature. DFT calculations suggest that this reaction proceeds through a Pd(0) -Pd(II) -Pd(III) pathway, in which the Pd(III) intermediate is responsible for reoxidizing Ir(II) to complete the Ir(III) -*Ir(III) -Ir(II) photoredox cycle.
