盐

A series of diazonium salts of 4-(N-methyl-N-phenylamino)-3-amino-1,8-naphthalic anhydride 5a, its naphthalimide derivative 5b, and 5e were designed and synthesized,and it was the first time to discover that aromatic radical-induced intramolecular aromatic 1, 5-hydrogen transfer was also involved in the nitrogen-contianed system during Pschorr cyclization.

实验设计合成了4--3-氨基-1，8-萘酐的重氮盐5a、其衍生物N-丁基-4--3-氨基-1，8-萘酰亚胺的重氮盐5b和N--4--3-氨基-1，8-萘酰亚胺的重氮盐5c，并首次发现了通过普朔尔环化反应以氮甲基化的氮为桥原子的体系存在着芳香自由基诱导的芳香1，5-氢转移。
