Selective 1,1- and 1,2-dibromination of phenylethanes by simply adjusting the reaction conditions has been developed. Mixtures of NaBr/NaBrO3/H2SO4 are employed as green bromination reagents, which can release Br2 or BrOH in situ as required without polluting the environment. Both the resulting 1,1- and 1,2-dibromoethyl arenes can be easily transformed to phenylacetylenes via elimination under basic
通过简单地调整反应条件,已经开发出苯乙烷的选择性 1,1- 和 1,2-二溴化。采用NaBr/NaBrO 3 /H 2 SO 4混合物作为绿色溴化试剂,可根据需要原位释放Br 2或BrOH,不污染环境。所得的1,1-和1,2-二溴乙基芳烃都可以在碱性条件下通过消除轻松转化为苯乙炔,具有巨大的工业应用潜力。
