OXIDATION OF HEXAMETHYLBENZENE AND 2,3,4,5,6-PENTAMETHYLBENZYL CATION IN FLUOROSULFONIC ACID

The oxidation of hexamethylbenzene in HSO3F-PbO2 takes place with the participation of the 1-H+-1,2,3,4,5,6-hexamethylbenzenonium ion and the intermediate formation of the 2,3,4,5,6-pentamethylbenzyl cation, which is capable of entering into further oxidative transformations leading to substitution of the hydrogen atom in two and three methyl groups.The structure of the final products from the observed transformations were established, and a mechanism is proposed for their formation.
