Within the proposed mechanism for the palladium‐catalyzed title reaction, the strained alkenenorbornene (or norbornadiene) enters and exits the catalytic cycle in a catalytic “square dance”, acting as both a promoter and a coupling partner in the formation of four carbon–carbon bonds, two of them by challenging CH activation processes.
