• 論文の詳細を見る

• The reactions of tropolones with tetrasulfur tetranitride gave 4<I>H</I>-cyclohepta[<I>c</I>][1,2,5]thiadiazol-4-ones, 6<I>H</I>-cyclohepta[<I>c</I>][1,2,5]thiadiazol-6-one, and 7<I>H</I>-cyclohepta[1,2-<I>c</I>: 3,4-<I>c</I>′]bis[1,2,5]thiadiazol-7-ones (9–56% yields) in one step. The yields of the products were not improved so much under high pressure and by the addition of a radical initiator.
