  • Title: Palladium-catalyzed electrophilic allylation reactions via bis(allyl)palladium complexes and related intermediates.
    Author: Szabó KJ.
    Journal: Chemistry; 2004 Oct 25; 10(21):5268-75. PubMed ID: 15372656.
    Abstract:
    The synthetic scope of the allyl-palladium chemistry can be extended to involve electrophilic reagents. The greatest challenge in these reactions is the catalytic generation of an allyl-palladium intermediate incorporating a nucleophilic allyl moiety. A vast majority of the published reactions that involve palladium-catalyzed allylation of electrophiles proceed via bis(allyl)palladium intermediates. The eta(1)-moiety of the bis(allyl)palladium intermediates reacts with electrophiles, including aldehydes, imines, or Michael acceptors. Recently, catalytic electrophilic allylations via mono-allylpalladium complexes were also presented by employment of so-called "pincer complex" catalysts.
