A catalyst system able to operate at temperatures as low as −65 °C for the Pd-catalyzed Kumada−Corriu cross-couplingreaction is described. This unprecedented level of activity allows the use of highly functionalized (Knochel-type) Grignard reagents. Additionally, the tolerance of the protocol toward a wide variety of functional groups allows for the synthesis of valuable compounds, including heterocyclic
