The classic approach to Pd-catalyzed difunctionalization reactions of alkenes, developed by Bäckvall, is to use dienes as substrates.2 In this case, the Pd alkyl formed upon initial nucleopalladation contains an adjacent alkene, and thus can form a π-allyl intermediate (A, Scheme 1). The π–allyl interaction stabilizes the intermediate and slows β-hydride elimination, while increasing the electrophilicity of the complex, allowing for attack by a second nucleophile. Examples of this approach are vast and include diacetoxylation, amino-acetoxylation, and amino-halogenation reactions.
