Abstract The bromoiodopropenoic acids (E)‐2‐bromo‐3‐iodopropenoic acid 5 and (Z)‐2‐bromo‐3‐iodopropenoic acid 6 were prepared by stereospecific nucleophilicsubstitution of the corresponding vinylic bromides. The structure of the (Z)‐isomer was confirmed by X‐ray crystallography.
摘要 通过相应乙烯基溴的立体有择亲核取代制备了溴碘丙酸 (E)-2-溴-3-碘丙酸 5 和 (Z)-2-溴-3-碘丙酸 6。(Z)-异构体的结构由 X 射线晶体学证实。
