A direct result: Alkylindiumreagents are synthesized by the insertion of indium into alkylhalide mediated by CuCl. The synthetic utility of these reagents is demonstrated by their palladium‐catalyzed coupling with arylhalides (see scheme). The reagents are compatible with various functional groups, and this makes the protocol generally useful in organic synthesis. DMA=N,N‐dimethylacetamide, TB

para-selective C(sp2)–H alkylation of electron-deficient arenes based on the electroreduction-enabled radical addition of alkyl bromides has been developed under mild conditions. In the absence of any metals and redox agents, the simple electrolysis system tolerates a variety of primary, secondary, and tertiary alkyl bromides and behaves as an important complement to the directed alkylation of the C(sp2)–H bond
