isomerization that possibly involved a radical mechanism but did not cause bond cleavage. The peracetic acid reaction increased the rate of trans-cis isomerization and was also accompanied by a minor cleavage of the side chain. Esterification did not have a substantial effect on the reactivity of ferulic acid, but 4-O-etherification significantly stabilized it against these two oxidants. By contrast
研究了阿魏酸及其衍生物与过氧化氢和过氧乙酸在木质素保持漂白条件下的反应,以确定它们对氧化降解的敏感性。阿魏酸及其醚化或酯化衍生物的共轭侧链显示相当稳定,尤其是对过氧化氢。主要反应是反式-顺式异构化,可能涉及自由基机理,但未引起键断裂。过乙酸反应增加了反式-顺式异构化的速率,并且还伴随有侧链的少量裂解。酯化对阿魏酸的反应性没有实质性影响,但是4-O-醚化显着稳定了它对这两种氧化剂的抵抗力。相比之下,
