Thiiranation of 2'-adamantylidene-9-benzonorbomenylidene (1) with 4,4'-dithiodimorpholine (5) in Ac 2 O at -15°C gave thiiranes 2 and 3 without the decomposition of the thermodynamically less stable 3. cis- and trans-Cyclooctenes underwent thiiranation with retention of their stereochemistry.
2'-金刚烷基-9-苯并降冰片亚甲基(1) 与 4,4'-二硫代二吗啉 (5) 在 -15°C 的 Ac 2 O 中的硫杂化反应得到硫杂丙环 2 和 3,而热力学不太稳定的 3 没有分解。反式环辛烯在保留其立体化学的情况下进行硫杂化。
