8‐tetrahydro‐2H‐thiocin; 9) can be prepared from thiocan‐5‐one (6) in three steps by applying the so‐called selenadiazole method. The heterocyclic alkyne can be oxidized to the corresponding sulfoxide 16 and sulfone 17. Due to their geometrical strain, all three cyclic alkynes show high reactivities in DielsAlder and 1,3‐dipolar cycloadditions. Moreover, tetrathiafulvalenes can be prepared from 9 and
1-硫代环辛-4-炔(= 5,6-二氢3,4,7,8-四氢-2 H-硫霉素; 9)可通过三步法从硫代5-1-(6)制备所谓的硒代二唑法。杂环炔可以被氧化成相应的亚砜16和砜17。由于它们的几何应变,所有三个循环炔表现出高反应性的Diels 桤木和1,3-偶极环。此外,可以通过与CS 2反应由9和16制备四硫富瓦烯。
