palladium complex catalyzes the title transformations, which are thought to proceed via a π‐allyl or π‐benzyl intermediate. The regioselectivity of the reaction (1,2‐ or 1,1‐difunctionalization) depends on the type of terminal double bond (conjugated or nonconjugated) in the substrate (see scheme) and appears to be controlled by the relative rates of β‐hydride elimination and transmetalation.
