This review summarizes recent applications of copper or copper-based compounds as a nonprecious metal catalyst in N-nucleophiles-based dehalogenation (DH) reactions of halogenated aromatic compounds (Ar-Xs). Cu-catalyzed DH enables the production of corresponding nonhalogenated aromatic products (Ar-Nu), which are much more biodegradable and can be mineralized during aerobic wastewater treatment or which are principally further applicable. Based on available knowledge, the developed Cu-based DH methods enable the utilization of amines for effective cleavage of aryl-halogen bonds in organic solvents or even in an aqueous solution.

The copper‐catalyzed arylation and vinylation of nitrogen nucleophiles is a highly versatile method for the construction of sp 2 C–N bonds. Copper‐catalyzed C–N bond formation has an extensive history and the field has been reinvigorated with the development of ligand‐promoted catalyst systems that provide general and effective reactions under relatively mild conditions. Copper promotes arylation and vinylation of a wide range of nitrogen nucleophiles, including amines, nitrogen heterocycles, and amide derivatives. The reactivity profile is complementary to that of palladium and often offers orthogonal chemoselectivity. This chapter presents a thorough overview of the copper‐catalyzed coupling of aryl and vinyl halides with nitrogen nucleophiles. Current understanding of the mechanism of this process is presented along with a detailed overview of the scope and limitations of this reaction along with optimal reaction conditions for the coupling of various nitrogen nucleophile classes.
