Imidoyl nitrates, formed by the reaction of imidoyl chlorides with AgNO3, rearrange via a unimolecular, intramolecular mechanism probably involving homolytic fission of the O–N bond to yield N-nitro amides; migration of the nitro group in N-arylimidoyl nitrates to the ortho- and para-positions of the N-aryl ring does not involve a special ortho-directing effect.
由亚氨基酰氯与AgNO 3反应形成的亚氨基硝酸根,可能通过单分子的分子内机制进行重排,可能涉及O-N键的均裂裂产生N-硝基酰胺。在硝基迁移Ñ -arylimidoyl硝酸盐到邻位-和对位的的位上Ñ芳基环不涉及特殊邻-directing效果。
