氧硫杂蒽及3—甲基氧硫杂蒽的合成研究

Study on the synthesis of phenoxatiin and 3-methyl-phenoxatiin

在无水AlCl3 催化剂存在下 ,二苯醚和间甲基二苯醚分别和硫反应 ,可高产率地合成氧硫杂蒽和 3—甲基氧硫杂蒽。考察了原料摩尔配比和催化剂的用量对产物产率及纯度的影响 ,并对反应机理进行了初步的探讨。

phenoxatiin and 3-methyl-phenoxatiin were prepared by diphenyl ether, 3-Methyl diphenyl ether and Sulphur with higher yield in the presence of dehydrated AlCl -3. The influences of material molecular ratio, quantity of catalyst and reaction temperature etc. on the action were discussed in detail, in addition, reaction mechanism was discussed preliminarily. ;
