4-Phenyl-1,2-dithiolium perchlorate reacts with ammonia in ethanol to yield 4-phenyl-isothiazole. The reaction is general for dithiolium salts. When unsymmetrical dithiolium salts are treated with ammonia, the major product and, under many conditions, the only product is the 5-substituted isothiazole. Of the four possible mechanisms for these reactions, an addition-elimination mechanism has been shown
4-苯基-1,2-二硫代高氯酸盐与乙醇中的氨反应生成4-苯基-异噻唑。该反应对于二硫鎓盐而言是一般的。当用氨处理不对称二硫鎓盐时,主要产物,在许多条件下,唯一产物是5-取代的异噻唑。在这些反应的四种可能机理中,已证明加成消除机理是正确的。用羟胺处理二硫鎓盐得到异恶唑和异噻唑的混合物。
