摘　　要：采用三苯基膦同溴素反应制备二溴三苯基膦,并以2-萘酚、6-溴-2-萘酚、2,6-二羟基萘和2,7-二羟基萘为原料,通过双分子取代反应制备2-溴萘、2,6-二溴萘和2,7-二溴萘。对反应条件及反应机理进行了探讨。2-Bromonaphthalene, 2,6-dibromonaphthalene and 2,7-dibromonaphthalene were prepared by bimolecular dis- placement reactions with triphenylphosphine dibromide used 2-naphthol, 6-bromo-2-hydroxynaphthalene, 2, 6-dihydroxy- naphthalene and 2,7-dihydroxynaphthalene as starting materi- als. Reaction mechanism and reaction conditions were investi- gated.
