New Route to Trimethylhydroquinone

Belyaev, E. Yu.,Tovbis, M. S.,Semichenko, E. S.,Orlovskaya, N. F.

, p. 506 - 507 (2007/10/03)

A new route to trimethylhydroquinone has been proposed that involves cycloaromatization of isonitrosoacetylacetone with methyl ethyl ketone to form 2,3,5-trimethyl-4-nitrosophenol, which is subsequently deoximated into 2,3,5-trimethyl-1,4-benzoquinone and then reduced to trimethylhydroquinone.
