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.
本发明提供了一种经济上和工业上优越的简单工艺,通过在温和条件下使芳香杂环化合物和硼化合物进行单步反应,同时仅改变原料的带电比例,就能以满意的产率和所需的比例选择性地生产芳香杂环单硼化合物和芳香杂环二硼化合物。本发明提供了一种杂芳基单硼或二硼化合物的生产工艺,该工艺由芳香杂环化合物和双(频哪醇)二硼或频哪醇二硼烷形式的硼化合物在含铱催化剂和配体如双吡啶配体的存在下组成。
