Abstract
Various monocyclic 1, 2-dithiines 6a, b, dt 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 to a significant extent on absorption in the visible ...
