Ubiquitous Benzoquinones, Multitalented Compounds for Palladium‐Catalyzed Oxidative Reactions

Abstract

Abstract Palladium(II)‐catalyzed procedures often use benzoquinone (BQ) to regenerate the catalyst. Besides its oxidation role, BQ can also promote various steps of the catalytic cycle. This review highlights the multifaceted properties of BQ and its analogues when involved in Pd II ‐catalyzed oxidative reactions and presents mechanisms proposed in the literature, in some cases with personal observations.
