摘要：

Where are the electrons that allow a highly reduced rhenium bipyridyl catalyst to attack CO2, but not H+? XAS and computational quantum chemistry indicate that the negative charge in [Re(bpy)(CO) 3]- and [Re(bpy-tBu)(CO)3]- is not stored in a localized Re 5d state, but rather in the bipyridine ligand. The active states of this family of catalysts possess formally Re0 metal centers with singly reduced bipyridine ligands. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
