Synthesis of Oligomers by Oxidative Dehydrogenation of Dihydric Phenols and Quinones with 3,3′,5,5′-Tetra-tert-butyl-trans-stilbenequinone

Oxidative dehydrogenation of pyrocatechol and 1,4-benzoquinone with 3,3′,5,5′-tetra-tert-butyl-trans-stilbenequinone as oxidant afforded oligomeric polyhydroquinones and polyquinones. Appropriate reaction conditions have been found, and the resulting olig

Synthesis of 3,3′,5,5′-Tetra-tert-butyl-4,4′-stilbenequinone and Its Catalytic Activity in the Liquid-Phase Oxidation of Inorganic Sulfides

The oxidation of 2,6-di-tert-butyl-4-methylphenol with hydrogen peroxide in the presence of potassium iodide gave 3,3′,5,5′-tetra-tert-butyl-4,4′-stilbenequinone which catalyzed liquid-phase oxidation of sodium sulfide with oxygen more efficiently than di

Reduction of 4,4′-stilbenequinone and 4,4′-diphenoquinone upon reaction with photogenerated radicals

The properties of 3,3′,5,5′-tetra-tert-butyl-4,4′- stilbenequinone (StQ) were studied by photochemical means. Acetone, acetophenone or benzophenone was photolyzed in the presence of both StQ and a donor, such as alcohols or triethylamine. This initiated reaction of a ketyl radical with StQ to form a semiquinone radical and eventually induce a permanent bleaching due to conversion of StQ to 4,4′-dihydroxystilbene (StQH2). The quantum yield of conversion of StQ to StQH2 increases with the donor concentration. Similar effects were found for the ketone-sensitized radical-induced conversions of the analogous diphenoquinone to the reduction product, diphenol.
