摘要

Addition of difluorocarbene to the title compound (7) at temperatures of 160-190" C yielded rearranged monoadducts having the norbornene and bicyclo [3.2. 0] hept-2-ene skeletons. Dechlorination of these compounds gave octafluoronorbornadiene (21) and octafluorobicyclo [3.2. 0] hepta-2, 6-diene (22). Though attempts to transform 22 into tropylium ion 1 met with failure, norbornadiene 21 was so transformed, as elaborated ...
