:The effect of the solvent on bromination of 6-methoxy -2-acyl naphthalene and 2-methoxyl naphthalene with 1,3-dibromo-5,5-dimethyl hydantoin was studied.6-Methoxy-5-bromo-2-acyl naphthalene and 1-bromo-2-methoxyl naphthalene were obtained by bromination of 6-methoxy-2-acyl naphthalene and 2-methoxyl naphthalene with 1,3-dibromo-5,5-dimethylhydantoin in a high yield,respectively.
考察了在不同极性溶剂中以1,3-二溴-5,5-二甲基海因作溴化剂对溴化6-甲氧基-2-酰基萘反应的影响。 1,3-二溴-5,5-二甲基海因作为溴化剂,在二氯甲烷、三氯甲烷、二氯乙烷中,于一定温度下,搅拌反应,高选择性溴化6-甲氧基-2-酰基萘的萘环,得到高收率的溴化产物6-甲氧基-5-溴-2-酰基萘。
