2-萘酚在甲醇或乙腈中加硝酸铈铵室温反应 10～ 15 h,可高收率地氧化偶联生成相应的联萘酚。 4例收率 89%～94%。但 2 -萘酚和 3-羟基 - 2 -萘酸甲酯的反应收率仅 47%萘酚用硝酸铈铵氧化生成联萘酚@王先恒
2-naphthol in methanol or acetonitrile plus cerium ammonium nitrate reaction 10 ~ 15 h at room temperature, high yields can be oxidative coupling generated corresponding binaphthol. 4 cases of 89% to 94% yield. However, the reaction yield of 2 - naphthol and methyl 3 - hydroxy - 2 - naphthoate was only 47%. Naphthol was oxidized by ammonium cerium nitrate to form binaphthol @ Wang Xianheng
