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