A novel procedure is suggested for the preparation of tetranuclear copper(II) μ4–oxo complexes Cu4OHal6L4 with N-heterocycles as ligands, consisting of the oxidation of piperidine or morpholine complexes of copper(I) halides with organic polyhalo compounds in the presence of water. The reaction proceeds readily even at room temperature giving the product in a high yield (up to 88%).
