Carbenylative Amination and Alkylation of Vinyl Iodides via Palladium Alkylidene Intermediates
Most palladium-catalyzed reactions involving insertion of alkylidenes with alpha-hydrogens undergo beta-hydride elimination from alkylpalladium(II) intermediates to form alkenes. Vinyl iodides were shown to generate eta3-allylpalladium intermediates that resist beta-hydride elimination, preserving the sp3 center adjacent to the carbene moiety. Acyclic stereocontrol (syn/anti) for carbenylative amination and alkylation reactions was low, suggesting a lack of control in the migratory insertion step. Highly hindered carbene precursors inexplicably led to formation of Z-alkenes with high levels of stereocontrol.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 52522-40-4
