cobalt‐catalyzed alkylation of aryl halides has been developed that proceeds smoothly in the presence of phosphanes or bipyridines as ligands with a variety of alkyl halides, including challenging alkyl electrophiles bearing β‐hydrogen atoms (see scheme). Sensitive functional groups are tolerated on both coupling partners, thus, significantly extending the general scope of transition‐metal‐catalyzed
已开发出一种直接用钴催化芳基卤化物进行烷基化的新方案,该方案在膦或联吡啶作为配体与各种烷基卤化物(包括带有β-氢原子的挑战性烷基亲电体)的存在下可以顺利进行。敏感的官能团在两个偶联配偶体上均具有耐受性,因此大大扩展了芳基卤化物的过渡金属催化烷基化作用的一般范围。
