Abstract:
We describe herein the efficient visible-light-responsive polyoxometalate-based multielectron photoredox catalysis induced by in situ coordination of alcohols to the lacuna of TBA4 H4 [γ-SiW10 O36 ] (I, TBA=tetra-n-butylammonium). The coordination of alcohols to the lacuna of I generated a new highest occupied molecular orbital as the electron donor level and enabled the visible-light-responsive multielectron transfer from alcohols to I, which could be utilized for aerobic alcohol oxidation and one-pot synthesis of N-arylimines starting from nitroarenes and primary alcohols.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
