The reaction of alkyl-substituted benzenes with o-chloranil at an elevated temperature was found to give 4,5,6,7-tetrachloro-1,3-benzodioxoles via benzylic oxidation and subsequent acetal formation, albeit in poor yields.
PHOSPHONIUM YLIDS, IV. The Reaction of Tetrahalo-o-benzoquinones with Diphenylmethylenetriphenylphosphorane and Fluorenylidenetriphenylphosphoranes. An Anomalous Behavior of the Wittig Reagent
