cross-coupling of nonactivated secondary alkyl bromides and iodides with alkynyl Grignard reagents at room temperature has been developed. A wide range of secondary alkyl halides and terminal alkynes are tolerated to afford the substituted alkynes in good yields. A slight modification of the reaction protocol also allows for cross-coupling with a variety of primary alkyl halides.
已经开发出一种简单的方案,用于在室温下将非活化的仲烷基溴化物和碘化物与炔基格氏试剂进行铁催化的交叉偶联。宽范围的仲烷基卤化物和末端炔烃是可接受的,以高收率提供了取代的炔烃。反应方案的略微修改也允许与多种伯烷基卤化物交叉偶联。
