Increased steric size of alkyl groups and the presence of coordinating atoms on alkoxy groups have both been found to contribute to decreasing yields of diquinones upon reaction of 2-alkyl-1,4-dialkoxybenzenes with CAN. The overall hydrophilicity of the substrates does not appear to be a significant factor in determining the diquinone yield for these reactions.

electronic nature of substituents present in 1,4-dimethoxybenzene derivatives has been found to have a profound effect on whether or not such substrates can be oxidized to diquinones using cericammoniumnitrate (CAN). In particular, there appears to be a correlation between the Hammett σp value of a substituent and the yield of the corresponding diquinone obtained upon treatment of the dimethoxybenzene
摘要 已经发现存在于 1,4-二甲氧基苯衍生物中的取代基的电子性质对这些底物是否可以使用硝酸铈铵 (CAN) 氧化成二醌具有深远的影响。特别是,在取代基的 Hammett σ p值与用 CAN 处理二甲氧基苯衍生物时获得的相应二醌的产率之间似乎存在相关性。该信息可以帮助预测给定的底物是否会在这种氧化时产生二醌。
