Abstract
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 thei r chemistry. The latter mode of sulfur extrusion depends to a signific ant extent on absorption in the visible region. Copyright (C) 1996 Els evier Science Ltd
