Various monocyclic 1,2-dithiines 6a,b,d-t were prepared via (Z,Z)-1,4-difunctionalized butadienes (4–11,19,20). A twisted cyclic structure A is unequivocally proved rather than of the ringopened valence isomer B. The reactivity of these 1,2-dithiines is described. Thermal as well as day-light induced sulfur extrusion is an important feature of their chemistry. The latter mode of sulfur extrusion depends
通过(Z,Z)-1,4-双官能化丁二烯(4-11,19,20)制备了各种单环1,2-二甲基6a,b,dt。甲扭曲环状结构甲明确地证明了,而不是ringopened价键异构体的乙。描述了这些1,2-二硫烷的反应性。热和日光诱导的硫挤出是其化学性质的重要特征。硫磺挤出的后一种模式在很大程度上取决于可见光区域的吸收。
