An XPS study of the charge and spin state of copper(II) β-diketonates and Cu(hfa)2 (hfa-hexafluoroacetylacetonate) complexes with imidazoline ligands is performed with comparison to the data of quantum chem. calculations It is shown that the structure of the spectra of copper is described by a superposition of the |2p53d9> and | 2p53d10L> electronic states determined by electron transfer processes between copper and L ligand atoms. It is found that during the coordination of imidazoline ligands to the Cu(hfa)2 complex the spin d. is redistributed through the chain of chem. bonds from the ligand nitroxyl group to the copper atom. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Application In Synthesis of copper(ii)hexafluor-2,4-pentanedionate).
copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. Copper catalyst has received great attention owing to the low toxicity and low cost. These ligands enable the reaction promoted in mild condition. The reaction scope has also been greatly expanded, rendering this copper-based cross-coupling attractive for both academia and industry.
