Palladium-catalyzed arylation of allylic cyclic carbonates with iodobenzene in the presence of Pd(OAc), as catalyst afforded the phenyl-substituted allylic alcohols via palladium oxygen β-elimination. However, palladium-catalyzed arylation, alkenylation, and alkynylation of allylic cyclic carbonates with iodonium tetrafluoroborates afforded the phenyl, alkenyl, and alkynyl-substituted allylic cyclic
在钯(OAc)存在下,钯催化烯丙基环状碳酸酯与碘苯的芳基化反应,通过钯氧β-消除作用提供苯基取代的烯丙基醇。但是,钯催化的芳基环状碳酸酯与四氟硼酸碘鎓的芳基化,烯基化和炔基化反应提供了苯基,烯基和炔基取代的烯丙基环状碳酸酯,而在水性和酸性条件下都没有还原性开环。
