| 摘 要： | 在催化量的铜粉存在下, 氟砜基二氟碘甲烷在DG、乙酐或不加溶剂时与烯烃反应,得到加成产物(3,4)和三元环产物。对反应机理作了初步探讨, 3,4经自由基加成得到而三元环产物是涉及二氟卡宾中间体。

| Abstract: | In the presence of copper, difluoroiodomethanesulfonyl fluoride reacted with olefins to give the 1:1 adducts and cyclopropane derivatives The mechanistic study showed that the addition products are formed by a radical chain process, and the others, involving difluorocarbene intermediate. |
