Organosodium compounds, generated by the oxidative addition of a C−Cl bond to Na, a halogen/Na exchange, or by direct sodiation using Na bricks or neopentylsodium in hexane, have been intercepted by various electrophiles, when working “on water” or in eutectic mixtures. These reactions display a broad substrate scope, under hydrous conditions at room temperature, short reaction times (20 s), high chemoselectivity
有机钠化合物是通过 C−Cl 键与 Na 的氧化加成、卤素/Na 交换或通过在己烷中使用钠砖或新戊基钠直接钠化而生成的,在“对水”或在水中工作时,已被各种亲电子试剂拦截。低共熔混合物。这些反应显示出广泛的底物范围,在室温含水条件下,反应时间短(20秒),化学选择性高,并且它们也是可扩展的。
