Copper(II) complex of 4‐(2,2′:6′,2“‐terpyridin‐4′‐yl)toluene(ttpy) was found to be a profitable catalyst for the N‐arylation of a variety of nitrogen‐containing heterocycles, such as some kinds of azoles and a secondary aliphatic amine, with aryl halides (iodides, bromides, and chlorides) under moderate conditions. A variety of functionalized aryl halides were tolerated in good to excellent yields by this air stable and low cost Cu(II)‐based catalytic system. Phenyl boronic acid was also used as an alternative to aryl halides to supply aryl moiety.
