The rhodium(I)‐catalyzed extrusion of carbon monoxide from biaryl ketones and alkyl/alkenyl arylketones was developed to produce biaryls and alkyl/alkenyl arenes, respectively, in high yields (see scheme). A wide range of functionalities are tolerated. Not only does this method provide an alternative pathway to construct useful scaffolds, but also offers a new strategy for CCbond activation.
