Palladium‐Catalyzed Carbonylation/Acyl Migratory Insertion Sequence

On the move: A palladium-catalyzed reaction of aryl iodides, diazo compounds or N-tosylhydrazones, and carbon monoxide affords β-oxo esters or ketones/enones (see scheme; DCE=1,2-dichloroethane). The products are delivered with high efficiency through the title sequence. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
