| Research Abstract |
1) A convenient symthesis of 1, 2-dithietes, which involves reaction of elemental sulfur with acetylenes carrying bulky substituents such as tert-butyl and 1-adamantyl, has been established.
2) It was found that ynamines such as bis(diethlamino)acetylene react with elemental sulfur to give the corresponding 1, 2-dithiocarbonyl compounds but not the 1, 2-dithietes. A similar reaction with elemental selenium was also found.
3) Convenient and practical syntheses of tetraarylthiophenes and tetraarylselenophenes, which involve reactions of diarylacetylenes with elemental sulfur and selenium, respectively, have been deveised. Application of the above method allowed the preparation of a star-burst type of thiophene oliogomers.
4) Acetylenediols such as 2, 5-dimethl-3-hexyne-2, 5-diol react with elemental sulfur to give substituted thieno[3, 2-b]shiophenes, thus providing a practical one-pot synthesis of thienothiophenes. The reaction is also applicable to the preparation of selenolo[3, 2-b]selenophenes.
5) 2-Chloro and 2-phenoxy substituted 1, 1-bis(diethylamino)ethylenes react with elemental sulfur to afford an inner salt, bis(diethylamino)carbeniumdithiocarboxylate in excellent yields.
