15N CIDNP effects observed during nitration of phenolic compounds with nitric and nitrousacid are comparable showing that nitrousacid is not only a catalyst during nitration with nitric acid but also a reactive intermediate. The 15N CIDNP effects are generated in radical pairs formed during encounters of NO2 and arene radical cations or aroxyl radicals. The mechanism given is valid for arenes more
在用硝酸和亚硝酸硝化酚类化合物的过程中观察到的15 N CIDNP效果相当,表明亚硝酸不仅是硝酸硝化过程中的催化剂,而且是反应性中间体。在15种ÑCIDNP效果在NO的遭遇过程中形成的自由基对生成的2和芳烃基团或阳离子基团aroxyl。给出的机理对于比甲苯更具反应性的芳烃有效。
