The fluorinated organic compounds are very attractive in pharmaceutical and agrochemical disciplines due to their unique thermal stability, solubility and reactivity, but the insertion of fluorine atoms remains as a great challenge. Recently, fluorination of organic substrates mediated by copper catalysts received considerable attention because of the regioselectivity, less harsh reaction conditions and better efficiency. Research results have indicated the high-valent copper-fluoride intermediates could be involved in the catalytic process. In our effort to better understand the possible catalytic mechanism, we used Cu(II) and Cu(I) complexes supported by a simple diamine ligand to react with fluorine reagents. Interesting color changes were observed. In addition, three new fluoro-bridged copper clusters were isolated and characterized by X-ray crystallography, UV-vis, EPR and FT-IR.
