New hydroacylation catalysts: Highly electron‐rich N‐heterocyclic carbenes (NHCs) facilitate the intermolecular hydroacylation of unstrained olefins. This unprecedented organocatalytic coupling joins simple and abundant aldehydes and styrenes to yield valuable ketone products. EWG=electron‐withdrawing group, EDG=electron‐donating group.
