The use of arylsulfonic acid salts as electrophiles in a nickel‐ or cobalt‐catalyzed cross‐coupling with Grignard reagents is described. Bis(tricyclohexylphosphine)nickel dichloride [NiCl 2 (PCy 3 ) 2 ] was found to be the optimal catalyst, and reactions with this catalyst proceeded in most cases at room temperature. The analogous cobalt catalyst [CoCl 2 (PCy 3 ) 2 ] was also found to promote the cross‐coupling reaction at higher temperature (60 °C).
