Abstract

The development of catalytic methods for the oxidation of organic compounds those fit contemporary environmental requirements represents a complicated and highly urgent task, especially for the processes of fine and pharmaceutical chemistry. This review summarizes data concerning the catalytic oxidation methods developed during the last 20 years for converting 2,3,6-trimethylphenol into 2,3,5-trimethyl-1,4-benzoquinone, a key intermediate for the synthesis of vitamin E. Also considered catalysts during 2,3,6-trimethylphenol hydroxylation in to 2,3,5-trimethyl-1,4-hydroquinone are considered, too.
