We have newly synthesized a series of N-[(N-nitrosoarylamino) methyl] succinimides, disclosing their syn and anti equilibria in a state of solution. It has been found that these nitrosoamines are capable of furnishing aromatic diazotates in basic media. By allowing the generating aromatic diazotates to react in situ, azo-couplings and triazene formations have been provided. The nitrosoamines behaved in acidic media to suffer a migration of the nitroso group similarly to the Fischer-Hepp migration.
我们新近合成了一系列N-[(N-亚硝基芳胺基)甲基]琥珀
酰亚胺,并揭示了它们在溶液状态下的syn和anti平衡。研究发现,这些亚
硝胺能在碱性介质中提供芳香重氮盐。通过使生成的芳香重氮盐就地反应,实现了偶氮偶联和
三氮烯的形成。在酸性介质中,这些亚
硝胺表现出类似Fischer-Hepp迁移的亚硝基团迁移现象。
