Abstract

Oxidations were carried out in CH2C12-aqueous NaOCl at le 1 5" C and pH 9A3 in the presence of 0.01 molar equiv of the commercially available radical 2b and 0.10 molar equiv of KBr. 1, 2-Diphenyl-l, 2-ethanediol affords benzoin or benzil in 85 and 97% yield, respectively, depending on the amount of aqueous NaOCl used (Table I, entries 1, 2). Hydroquinone is easily oxidized to 1, 4-benzoquinone in almost quantitative yield (entry 3) ...
