to the more conventional palladium and nickel in the cross‐coupling arena, the major limitation is the necessity for carcinogenic N‐methylpyrrolidone as a co‐solvent in the vast majority of catalytic reactions. Herein, we introduce N‐methylcaprolactam as an efficient, non‐toxic and practical dipolar aprotic solvent for iron‐catalyzed C(sp2)−C(sp3) alkylative cross‐coupling of aryl chlorides and tosylates

serves as a highly effective substitute for NMP in iron-catalyzed C(sp2)–C(sp3) cross-coupling of aryl chlorides with alkyl Grignardreagents. This challenging alkylation proceeds with organometallics bearing β-hydrogens with efficiency superseding or matching that of NMP with ample scope and broad functional group tolerance. Appealing applications are demonstrated in the cross-coupling in the presence
