5-tetrathiabicyclo[4.4.0]decane, and 2,3,4,5,6-pentathiabicyclo[5.4.0]undecane, were synthesized in high yields by new reactions of their corresponding dithiols and related compounds, 1,3-benzodithiole-2-thiones (5) and 1,3-dithiolane-2-thione, with elemental sulfur in liquid ammonia at ambient temperature. In the synthesis of 3a–d from 1,2-benzenedithiol or 5, considerable increase in the product yield
许多环状多硫化物,即苯并五硫菌素 (3a–d)、6H-1,2,3,4,5-苯并五硫菌素,5H-1,2,3,4-苯并四硫菌素,3H-1,2-苯并二硫醇,1,5 -dihydro-2,3,4-benzotrithiepin, 1,4-dihydro-2,3-benzodithiin, naphtho[1,8-cd]-1,2-dithiole, 1,2,3-trithiane, 1,2-二噻烷、2,3,4,5-四硫双环[4.4.0]癸烷和2,3,4,5,6-五硫双环[5.4.0]十一烷通过其相应的二硫醇和相关化合物,1,3-苯并二硫醇-2-硫酮 (5) 和 1,3-二硫戊环-2-硫酮,在室温下在液氨中含有元素硫。在由 1,2-苯二硫醇或 5 合成 3a-d 时,在后处理中使用的溶剂中加入 1,3-二硝基苯后,观察到产物产率显着增加。
