【摘要】 <正> 作者前曾报道,三溴化三乙基苄铵（PhCH₂Et₃NBr₃^-,TEBABr₃,1）和三碘化三乙基苄铵（TEBAL₃）能作为有效的溴代和碘代试剂而与芳胺反应,以高产率生成多溴代和多碘代芳胺。在进一步对TEBABr₃在有机合成更多还原

【Abstract】 A catalytic oxidation involving the reaction of triethylbenzylammonium tribro-mide and benzoins in the presence of benzoyl peroxide is described. A variety of benzils areprepared in good yields by the title reaction. A possible reaction mechanism is proposed.更多还原
