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.
