Abstract

A catalytic system consisting of CoCl2 ⋅2 LiCl (5 mol %) and HCO2 Na (50 mol %) enables the cross-coupling of various N-heterocyclic chlorides and bromides as well as aromatic halogenated ketones with various electron-rich and -poor arylzinc reagents. The reactions reached full conversion within a few hours at 25 °C.
