Abstract

An efficient σ-Lewis acidic Ag(I) complex has been obtained by complexation with an electron-donating π-conjugated molecule as a side-on π ligand. The σ-Lewis acidity is possibly derived from the controlled linear coordination around Ag(I) due to the π ligand. A combination of UV-Vis absorption spectroscopy and X-ray absorption near-edge structure analyses clearly revealed that the complex is formed by π ligand-to-Ag(I) charge-transfer interaction. The σ-Lewis acidity was evaluated by IR spectroscopy using 2,6-dimethyl-γ-pyrone as the σ-Lewis basic molecule.
