The present invention provides an economically and industrially superior simple process that enables the selective production of an aromatic heterocyclic monoboron compound and aromatic heterocyclic diboron compound at a satisfactory yield and in a desired ratio by reacting an aromatic heterocyclic compound and a boron compound in a single step under mild conditions while changing only the charged ratios of the raw materials. The present invention provides a production process of a heteroaryl mono- or diboron compound comprising an aromatic heterocyclic compound and a boron compound in the form of bis(pinacolate)diboron or pinacolate diborane in the presence of a iridium-containing catalyst and a ligand such as a bipyridyl ligand.
