3-diene and hexafluorocyclobutene interact with elemental sulphur under conditions of mutual conversion (⩾280 °C) to give the same products, hexafluoro-3,6-dihydro-1,2-dithiine (1), hexafluorothiolene-3 (2) and hexafluorothiolanethione (3). The product composition and ratio depend on the reaction conditions. Dithiine 1 and thiolene 2 were formed in competitive reactions. Their thermal stability and
在相互转化的条件下(⩾280°C),六氟丁烯-1,3-二烯和六氟环丁烯与元素硫相互作用,得到相同的产物六氟-3,6-二氢-1,2-二硫氨酸(1),六氟噻吩-3 (2)和六氟硫代乙硫磷(3)。产物组成和比例取决于反应条件。在竞争反应中形成了二硫氨酸1和硫代烯2。研究了它们的热稳定性和二硫氨酸1的逆向加成反应。后者反应产生硫代2除形成六氟环丁烯外。这与逆向加成以及环加成反应的逐步机理是一致的。
