Thiele–Winter acetoxylation of quinones. Part V. Structures of the major triacetate product from 5-methyl-3-t-butyl-1,2-benzoquinone and of the by-product from 2-methyl-6-t-butyl-1,4-benzoquinone

Abstract

It has been confirmed that Thiele–Winter acetoxylation of 5-methyl-3-t-butyl-1,2-benzoquinone gives 1,2,4-triacetoxy-5-methyl-3-t-butylbenzene. The by-product from 2-methyl-6-t-butyl-1,4-benzoquinone has been shown to be 2-(2-ethoxy-2-methylpropyl)-6-methylhydroquinone (10), formed by photoreaction in ethanol.
