The monoanion of the alkanedithioic acid 1a is oxidized with hypervalent iodine compounds to form the 1,2-dithiine 6, the monoanion of 1b yields the 1,2,4-trithiolane 7 and the dianions 2b, c furnish the 1,2,4,5-tetrathianes 3b, c. With diphenyltin or dimethyltin dichlorides 8 the monoanions of 1b, c afford the monothioacyl or bisthioacyl organotin sulfides 10a–c or 11a, b respectively. When treated
所述alkanedithioic酸的单价阴离子1A与高价碘化合物氧化以形成1,2- dithiine 6,的单价阴离子1b中产生的1,2,4- trithiolane 7和二价阴离子2b中,C提供1,2,4- ,5-四硫杂环丁烷3b,c。与二苯基锡或二甲基二氯化锡8的1b,c的单阴离子分别生成单硫酰基或双硫酰基有机锡硫化物10a-c或11a,b。当用六甲基二硅氮烷锂处理时,10b发生分子内环化成1,3,2-二硫代锡烷9b; 10a被三乙胺去质子化为1,3,5-trithia-2-stanninane 13。二价阴离子2c与二氯化二苯基锡8反应,生成1,3,2-二硫杂锡碳烷9d,与二氯化二甲基锡形成1,2,4-三硫杂环戊烷16。图9d是由亚硫酰氯,二氯化硫,和二氯化二硫裂解以得到1,2,4,5- tetrathiane的复杂混合物3C和环状多硫化物1,2,3,4,5,6- hexathiepane
