Oxidation reactions of 2,4,6-tri-t-butylaniline with lead tetraacetate (LTA), lead tetrabenzoate (LTB), peroxybenzoic acid (PBA) and benzoyl peroxide (BPO) were studied and mechanisms of these reactions were briefly discussed. In the reaction with LTA, 4-acetoxy-1-imino-2,4,6-tri-t-butyl-2,5-cyclohexadiene (I), 2-acetamido-3,5-di-t-butylphenol (II) and 2-acetylimino-3,5-di-t-butyl-3,5-cyclohexadienone(III) were produced. Oxidation with LTB gave 4-benzoyloxy-1-imino-2,4,6-tri-t-butyl-2,5-cyclohexadiene (VI, major product) and 2-benzamido-3,5-di-t-butylphenol (VII). The reaction products with PBA were 2,4,6-tri-t-butylnitrosobenzene (VIII) and VII. In addition to the last two compounds, VI and 2,2′,4,4′,6,6′-hexa-t-butylazobenzene (XI) were obtained in the case of BPO.
研究了2,4,6-三叔丁基苯胺与四乙酸铅(LTA)、四苯甲酸铅(LTB)、过苯甲酸(PBA)和过氧化苯甲酰(BPO)的氧化反应,并简要讨论了这些反应的机理。与LTA反应,4-乙酰氧基-1-亚氨基-2,4,6-三叔丁基-2,5-环己二烯(I)、2-乙酰氨基-3,5-二叔丁基苯酚(II) )和2-乙酰亚氨基-3,5-二叔丁基-3,5-环己二烯酮(III)被生产。用LTB氧化得到4-苯甲酰氧基-1-亚氨基-2,4,6-三叔丁基-2,5-环己二烯(VI,主要产物)和2-苯甲酰氨基-3,5-二叔丁基苯酚(七)。与PBA的反应产物为2,4,6-三叔丁基亚硝基苯(VIII)和VII。除了最后两种化合物外,在 BPO 的情况下还获得了 VI 和 2,2',4,4',6,6'-六叔丁基偶氮苯 (XI)。
