Organocopper reagents from phenols: A new cobalt‐catalyzed arylsulfonate/copperexchange reaction allows the synthesis of highlyfunctionalizedarylcopperreagents from sulfonates bearing electron‐deficient substituents under mild conditions (25–45 °C, 1–6 h; see example). Sensitive functional groups, such as aldehydes, esters, and nitriles, are well‐tolerated.
