Magnesium in methanol was found to be an effective and inexpensive reagent for the dehalogenation of (hetero)aryl chlorides, bromides and iodides under mild conditions. The halogen/hydrogen exchange proceeded at room temperature and tolerated functional groups such as esters, nitriles, alcohols, and alkenes.

（杂）芳基卤化物在室温下用镁/甲醇进行脱卤

发现甲醇中的镁是在温和条件下对（杂）芳基氯化物，溴化物和碘化物进行脱卤作用的有效且廉价的试剂。卤素/氢交换是在室温下进行的，并具有可耐受的官能团，例如酯，腈，醇和烯烃。
