The thioenols derived from cyanomonothiocarbonylmalonamides and a cyanodithiocarbonylmalonamide were found to be very reactive species. They react under a variety of conditions such as crystallization, reaction with several carbonyl compounds, and reactions with another thioenol molecule to give a variety of products, mostly heterocycles, including substituted 2,3-dihydroisothiazole-3-ones and 3-thione
发现衍生自氰基单硫代羰基丙二酰胺和氰基二硫代羰基丙二酰胺的硫醇是非常活泼的物质。它们在各种条件下反应,例如结晶,与几种羰基化合物反应以及与另一个硫烯醇分子反应,从而产生各种产物,主要是杂环化合物,包括取代的2,3-二氢异噻唑-3-酮和3-硫酮2 -取代的亚甲基噻唑,3,4-二氢-1,3-噻嗪-4-酮和4-硫酮,二乙烯基硫醚,1,2-二硫杂环戊烷基和3,7-二氮杂[3.3.0]双环辛烷衍生物。这些反应建议的机制包括自由基机制,亲核取代和缩合。
