摘要
研究了磁性纳米Fe3O4促进的2-萘酚氧化偶联合成2,2’-二羟基-1,1’-联萘(BINOL)的反应,反应以空气中的O2为氧化剂,无溶剂的固相条件下进行。结果表明,在优化条件下:反应温度130℃,反应时间3.5 h,n(2-萘酚)∶n(Fe3O4)=1.7∶1,BINOL的收率达到99.0%,且磁性纳米Fe3O4连续循环使用5次,BINOL的收率无明显降低。
Magnetic Fe3 O4 nanoparticles promoted solid-state synthesis of BINOL was studied,with 2-naphthol as substrate and oxygen in air as oxidant. Result showed that the optimized conditions were as follows：130 ℃,3. 5 h and n（2-naphthol）：n（ Fe3 O4 ）=1. 7：1,the yield of BINOL up to 99. 0%. The separated magnetic Fe3 O4 nanoparticles can be recycled for 5 runs in the synthesis of BINOL reaction and the yield of BINOL without significantly decrease.
