An unexpected reaction of N,N-disubstituted hydrazine with naphthol and its analogues under simply thermal conditions has been disclosed. 2-Naphthol reacted with various N,N-disubstituted hydrazines under argon to afford 1-amino-2-naphthol and the corresponding secondary amines in excellent yields. Ortho amination of 2-naphthols, hydroxyquinoline, and naphthalenamine occurred when they reacted with
N,N-二取代肼与萘酚及其类似物在简单的热条件下的意外反应已经公开。2-萘酚在氩气下与各种 N,N-二取代肼反应,以极好的收率得到 1-氨基-2-萘酚和相应的仲胺。2-萘酚、羟基喹啉和萘胺与 N-甲基-N-苯肼反应时发生邻位胺化。
