P-Toluenesulfonic anhydride Usage And Synthesis
Chemical PropertiesOff-white to cream powder
Usesp-Toluenesulfonic anhydride has been employed as reagent in palladium-catalyzed allylic alkenylation of allylic alcohols with n-butyl acrylate.
General Descriptionp-Toluenesulfonic anhydride acts as electrophilic species and activates 2-deoxy-sugar hemiacetals in situ, which reacts stereoselectively with nucleophilic acceptors to afford β-anomers.
