In the previous papers of this series2 it has been shown that when the polymethylbenzenes containing four or five methyl groups are allowed to stand in contact with concd. sulfuric acid, they first sulfonate, and then the sulfonic acids rearrange. These rearrangements are of at least two types: the first, shown by pentamethylbenzene, involves the migration of a methyl group from one molecule to another, while the second, shown by the tetramethylbenzenes ...
