顺式环辛烯与S8 O在二硫化碳中反应生成顺式9,10,11-三硫杂双环[6.3.0]十一烷(1,2,3-三硫杂环戊烷)。用间氯过苯甲酸(MCPBA)或二甲基二环氧乙烷(DMD)氧化1,2,3-三硫杂环戊烷产生相应的1-外氧化物、1-内氧化物、2-内氧化物、2-外氧化物、1-内,3-外二氧化物、1-外,3-外二氧化物、1,1,3-外三氧化物和1,1,3,3-四氧化物,取决于氧化剂的量。在用MCPBA氧化1-内氧化物时,观察到另一种1,3-二氧化物的形成,可归因于1-内,3-内二氧化物。用DMD氧化2-外氧化物以低产率得到1,1,3,3-四氧化物。用LiAlH 4还原1,2,3-三硫杂环戊烷及其反式异构体,以高产率分别得到顺式和反式环辛烷-1,2-二硫醇。用MCPBA氧化顺式-1,2-二硫醇的钠盐,以低收率提供相应的1,2,5,6-四硫代辛烷作为唯一可鉴定的产物。
cis-Cyclooctene reacted with S 8 O in refluxing carbon disulfide to give cis-9,10,11-trithiabicyclo[6.3.0]undecane (1,2,3-trithiolane). Oxidation of the 1,2,3-trithiolane with m-chloroperbenzoic acid (MCPBA) or dimethyldioxirane (DMD) yielded the corresponding 1-exo-oxide, 1-endo-oxide, 2-endo-oxide, 2-exo-oxide, 1-endo,3-exo-dioxide, 1-exo,3-exo-dioxide, 1,1,3-exo-trioxide, and 1,1,3,3-tetraoxide, depending on the amount of the oxidants. Formation of another 1,3-dioxide assignable to the 1-endo,3-endo-dioxide was observed in the oxidation of the 1-endo-oxide with MCPBA. Oxidation of the 2-exo-oxide with DMD gave the 1,1,3,3-tetraoxide in low yield. Reduction of the 1,2,3-trithiolane and its trans isomer with LiAlH 4 gave cis- and trans-cyclooctane-1,2-dithiol, respectively, in high yields. Oxidation of the sodium salt of the cis-1,2-dithiol with MCPBA provided the corresponding 1,2,5,6-tetrathiocane in low yield as the only identifiable product.
