Azoxybenzenes (1) were heated at 245–250 °C to give azobenzenes (2), 2-hydroxyazobenzenes (3), 2-hydroxy-azoxybenzenes (4), 4-hydroxyazobenzenes (5), and 4-hydroxyazoxybenzenes (6). Compounds 4 and 6 were mostly composed of α-isomers. In the reaction of azoxytoluenes, their methyl groups were oxidized to formyl groups. It was proposed that 4 and 6 were the intermediates of the thermal rearrangement
偶氮苯 (1) 在 245–250 °C 下加热,得到偶氮苯 (2)、2-羟基偶氮苯 (3)、2-羟基偶氮苯 (4)、4-羟基偶氮苯 (5) 和 4-羟基偶氮苯 (6)。化合物4和6主要由α-异构体组成。在偶氮甲苯的反应中,它们的甲基被氧化成甲酰基。有人提出4和6是1到3和5热重排的中间体。
