AB The scandium triflate-catalyzed cycloaddition reactionof polycyclic 1,2-dithiolethiones to maleimides is described. Thereaction constitutes an easy approach to linear as well as branchedoligomeric cis-fused dihydro[1,3]dithiolo[4,5-c]pyrrole-4,6-dionerings interconnected by 3,5-diylidenethiomorpholine-2,6-dithione orylidene-6-thioxo[1,2]dithiolo[3,4-b][1,4]thiazin-3-one groups. Thepresence of highly colored, highly polarized push−pull α,β-unsaturated thione groups in their structures make these compoundssensitive to the presence of mercury(II) cation in organic or mixedorganic/aqueous solvents.
