A highly efficient catalytic system for the N-arylation reactions of (hetero)aryl chlorides and nitrogen heterocycles with a copper(I) complex containing a 1,10-phenanthroline analogue N-heterocyclic carbene (NHC) has been reported. The complex was characterized by 1H NMR and 13C NMR spectroscopy and elemental analysis, and its structure was determined by single-crystal X-ray diffraction. The NHC-copper(I) complex was employed as pre-catalyst for Ullmann type N-arylation reactions of (hetero)aryl chlorides with various azoles. A variety of hindered and functionalized azoles and (hetero)aryl chlorides were transformed in good to excellent yields.

The first application of α-d-galacturonic acid hydrate (GalA) is reported here, as a potential O-donor ligand. The C-N couplings of N-heterocycles with aryl halides or arylboronic acids could be readily conducted and exhibited good functional group tolerance with characters of selectivity. These N-Arylazoles allow rapid access to several pharmaceutical intermediates and can be easily transformed into a variety of other interesting scaffolds as well.
