Insights into the Palladium(II)-Catalyzed Wacker-Type Oxidation of Styrene with Hydrogen Peroxide and tert-Butyl Hydroperoxide.

ABSTRACT: Wacker oxidations are ubiquitous in the direct synthesis of carbonyl compounds from alkenes. While the reaction mechanism has been widely studied under aerobic conditions, much less is known about such processes promoted with peroxides. Here, we report an exhaustive mechanistic investigation of the Wacker oxidation of styrene using hydrogen peroxide (H₂O₂) and tert-butyl hydroperoxide (TBHP) as oxidants by combining density functional theory and microkinetic modeling. Our results with H₂O₂ uncover a previously unreported reaction pathway that involves an intermolecular proton transfer assisted by the counterion [OTf]^- present in the reaction media. Furthermore, we show that when TBHP is used as an oxidant instead of H₂
