We report a remote arylation in less than 10 min reaction time at room temperature over a distance of up to 11 carbons. The unprecedentedspeed is enabled by the air-stable PdI dimer [Pd(μ-I)(PCy2tBu)]2.

perspective yet rarely exploited partners in transition-metal catalyzed cross-coupling reaction. The notoriously low nucleophilicity of alkylzirconocenes and the potential β-H elimination restrict their application in cross-coupling. Herein, we report the first Pd-catalyzed aryl-alkyl cross-coupling of alkylzirconocenes and aryl halides. A commercially available N-heterocyclic carbene (IPr) as the ligand
