The formation of orthoquinones in the dimethyldioxirane oxidation of phenols
Crandall, Jack K.,Zucco, Martine,Scott Kirsch,Coppert, David M.
, p. 5441 - 5444 (2007/10/02)
The dimethyldioxirane oxidation of selected phenols provides the corresponding orthoquinones. This conversion proceeds via the related arenediols, which are cleanly oxidized to the quinones by this oxidant.
