The reactions of 2-cyano-2-dimethylamino-1,3-dithiolane (2) with electrophiles (organic halides and perchloric acid) and nucleophiles were investigated. It was found that 2 dissociated partially to 2-dimethylamino-1,3-dithiolan-2-ylium (1) and cyanide ions in polar solvents. In the reactions of 2 with electrophiles, nitriles were obtained along with the formation of salts of 1. The reactions of 2 with
研究了 2-cyano-2-dimethylamino-1,3-dithiolane (2) 与亲电试剂(有机卤化物和高氯酸)和亲核试剂的反应。发现 2 在极性溶剂中部分离解为 2-二甲氨基-1,3-dithiolan-2-ylium (1) 和氰化物离子。在 2 与亲电试剂的反应中,随着 1 的盐的形成,得到腈。 研究了 2 与亲核试剂的反应,因为 2 被认为是阳离子 1 的前体。在某些情况下,它的反应性不同于高氯酸盐的 1。讨论了一种机制,其中氰化物离子可能充当从亲核试剂中提取质子的碱。
