stability on the disulphide group. The stability of the 3,5-diamino-or 3,5-di(methylamino)-1,2- dithiolylium salts is greater than that of the 4-chloro-3, 5-diamino- or 3,5-di(methylamino)-1,2-dithiolylium salts. The reduction of these salts occurs in one two-electron wave. Mono- and bis-dithiolylium salts of tetrachloro-ferrate(III), -cobaltate(II), -niccolate(II), and -cuprate(II) have also been prepared
3,5-二氨基-或3,5-二(甲基氨基)-1,2-二硫代高氯酸盐或溴化物与4-氯-(或4-溴-)3,5-二氨基或3.5-二(甲基氨基)的盐基)-1,2- dithiolylium氯化物或溴化物已经制备由dithiomalonamide或oxyation NN '-dimethyldithiomalonamide。报告了电导率,分子量,1 H nmr,uv,ir和极谱测量。从CH 2中去除质子的二硫代丙二酰胺基团得到具有假芳香特性的五元环。所有实验数据都支持硫原子之间相当大的π键。这赋予了二硫化物基团极大的稳定性。3,5-二氨基-或3,5-二(甲基氨基)-1,2-二硫基lium盐的稳定性大于4-氯-3、5-二氨基-或3,5-二(甲基氨基)的稳定性)-1,2-二硫代lylium盐。这些盐的还原发生在两个电子波中。还已经制备了四氯高铁酸酯(III),-钴酸酯(II),-烟酸酯(II)和-铜酸酯(
