In the presence of a catalytic amount of InCl3·4H2O, trioxane was first used as the methylating agent for multimethylated aromatic compounds such as pentamethylbenzene, 1,2,4,5-tetramethylbenzene and 1,3,5-trimethylbenzene to afford hexamethylbenzene in fair to high yields.
在催化量的InCl3·4H2O存在下,首先使用
三恶烷作为多甲基化芳族化合物(如
五甲基苯,1,2,4,5-四甲基苯和1,3,5-三甲基苯)的甲基化剂,公平地得到
六甲基苯高产。
