一提到氢化钠（NaH）的用途，很多的有机化学工作者第一反应就是可以用来拔氢。然而，NaH除了作碱以外，还可以作为亲核试剂进攻亲电试剂。近期，新加坡南洋理工大学的Shunsuke Chiba教授课题组在Angew. Chem. Int. Ed. 上报道了NaH还原卤代芳烃的氢化去卤化反应，过程中使用碘化物（MI，M = Li, Na）作添加剂（Scheme 1c）。

When it comes to the use of sodium hydride (NAH), the first reaction of many organic chemists is to extract hydrogen. However, in addition to being a base, nah can also be used as a nucleophile to attack electrophiles. Recently, Professor Shunsuke Chiba of Nanyang University of technology in Singapore reported on angelw. Chem. Int. ed. the hydrogenation dehalogenation of halogenated aromatics by NAH reduction, in which iodide (MI, M = Li, Na) was used as an additive (scheme 1c).
