An operationally simple protocol for a palladium-catalyzed 13CO and 14CO exchange with activated aliphatic and benzoic carbonyls is presented. Several 13C and 14C building blocks, natural product derivatives, and pharmaceuticals have been prepared to showcase the method for late-stage carbonisotope incorporation and its functional group compatibility.
