- 論文の詳細を見る
Thioacylketene thioacetals (<B>7</B>) and <I>N</I>-Thioacyldithioimidocarbonates (<B>8</B>) undergo 1,4-cycloaddition reactions with active acetylenes and olefins to give six-membered heterocycles. Tetracyanoethylene behaves in a different way to afford conjugated dienes. In the reactions with diphenylketene and diazo compounds, <B>7</B> and <B>8</B> undergo different types of reactions; <B>7</B> gave products derived from 1,2-cycloaddition to the C=S bond, while <B>8</B> afforded 1,4-cycloadducts. Compound <B>7</B> was found to be more reactive than <B>8</B>. The reactivity difference between <B>7</B> and <B>8</B> is discussed.
