iodocyclization reactions of functionalized acetylenic derivatives with ICl are disfavored in comparison with the corresponding electrophilic addition reactions providing regioselectively (E)-1-chloro-2-iodoethene derivatives. On the contrary, 6-endo-digand 5-exo-dig iodocyclizations of methyl ynoates with ICl seem to be favored in comparison with the corresponding electrophilic addition reactions.
与提供区域选择性的(E)-1-氯-2-碘乙烯衍生物的相应亲电加成反应相比,官能化的炔属衍生物与ICl的6-Exo-dig和/或7-endo-dig碘环化反应是不利的。相反,与相应的亲电加成反应相比,用ICl对甲基丙烯酸甲酯的6-内-digo-和5-exo-dig碘环化似乎是有利的。
