development of an electrochemical methodology for XEC that utilizes redox-active shuttles developed by the energy-storage community to protect reactive coupling catalysts from overreduction. The resulting electrocatalytic system is practical, scalable, and broadly applicable to the reductive coupling of a wide range of aryl, heteroaryl, or vinylbromides with primary or secondary alkyl bromides. The impact

cross-electrophile coupling between alkylsulfones and aryl bromides. The use of alkylsulfones offers strategic advantages over other alkyl electrophiles as they can be incorporated into molecules in unique ways and permit α-functionalization prior to coupling. The conditions developed here enable incorporation of a wide array of aromatic rings onto (fluoro)alkyl scaffolds with broad functional group

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

primary alkylated arenes plays an important role in the molecular action of drugs and natural products. The nickel/spiro-bidentate-pyox catalysed cross-electrophile coupling of aryl bromides and primary alkylbromides was developed for the formation of the Csp2–Csp3 bond, which provided an efficient method for the synthesis of primary alkylated arenes. The reactions could tolerate functional groups

Convergent paired metal electrocatalysis enables the direct use of simple primary and secondary aliphaticacids as coupling partners for C(sp2)−C(sp3) bond formation by radical decarboxylation. This new electrophotocatalytic method features a broad substrate scope, wide functional-group tolerance, and could be used for late-stage functionalization of complex molecules.
