| Abstract: | Cyclic carbonates substituted with 1,3-butadienyl moiety were synthesized by a palladium-catalyzed reaction of dienylic carbonates including a carbon dioxide elimination-fixation process. The reaction proceeded via a migration-isomerization of the resulting π-allylpalladium intermediates to afford trans-1,3-dienyl-substituted cyclic carbonates in a selective manner. |
