Singlet Diradical Character of an Oxidized Ruthenium Trithiolate:Electronic Structure and Reactivity

摘要

The nucleophilicity of transition-metal thiolates has been attributed to a metal-sulfur d-p pi interaction,which results in high sulfur character for the occupied frontier orbitals.Consequently,oxidation of metal thiolates may be either sulfur-or metal-centered.Recent studies have focused on the stabilization and characterization of metal-coordinated phe-nylthiyl radicals and related complexes.
