The following are new results developed by the present project.
1. Sulfuration of anti- and syn-9,9'-bibenzonorbornenylidenes by elemental sulfur produced episulfides in high yields with retention of the configuration of the original alkenes.
2. Treatment of di-1-adamantylacetylene with disulfur dichloride furnished 2,3-di-1-adamantyl-thiirene 1-oxide, 3,4-di-1-adamantyl-1,2-dithiete, and 1,2-di-1-adamantyl-2-thioxoethanone.
3. Oxidation of tetrathiolanes, carrying two bulky substituents at the 5-position, with dimethyldioxirane, produced the corresponding tetrathiolane 3,4-dioxides, the first vic-disulfoxide isolated in pure form. The 3,4-dioxides decomposed in solution at room temperature to give dithiirane 1-oxides and a reactive species "SィイD22ィエD2O". Deoxygenation of the dithiirane 1-oxides with Lawesson's reagent provided dithiiranes.
4. Ring inversion energies of the trithiolane and pentathiepane rings were determined. A pair of conformational isomers was synthesized by making use of high inversion barrier of the pentathiepane ring.
5. Monocyclic thiophene 1-oxides, 1-imides, and related species were synthesized, and their structures and reactivities were investigated.
6. The parent thiophene 1,1-dioxide and monosubstitued derivatives were synthesized and isolated for the first time, and their spectroscopic properties and reactivities were fully characterized.
7. A wide variety of sulfur-containing large-membered heterocycles, such as thiophenophanes and crown thioethers, were synthesized.
