- 論文の詳細を見る
Benzotris- (<B>3</B>) and benzobis[1,2,5]thiadiazole (<B>4</B>) were prepared in a moderate yield, respectively, by the reaction of tetrasulfur tetranitride (<B>5</B>) with halocatechols (<B>6</B>) and -resorcinols (<B>7</B>). The reduction of <B>3</B> and <B>4</B> with Sn powder in a mixture of concentrated hydrochloric acid and dioxane gave benzenehexamine (<B>1</B>) and 1,2,3,4-benzenetetramine (<B>2a</B>) and its 5-methyl derivative (<B>2b</B>) in good yields, as a stable tri- (<B>1</B>·<B>3HCl</B>) and dihydrochloride (<B>2</B>·<B>2HCl</B>), respectively.
