cobalt‐catalyzedalkylation of aryl halides has been developed that proceeds smoothly in the presence of phosphanes or bipyridines as ligands with a variety of alkylhalides, 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
