development of efficient and selective C-N bond-forming reactions from abundant feedstock chemicals remains a central theme in organic chemistry owing to the key roles of amines in synthesis, drug discovery, and materials science. Herein, we present a dual catalyticsystem for the N-alkylation of diverse aromatic carbocyclic and heterocyclic amines directly with carboxylicacids, by-passing their preactivation
