Abstract

original image

One to two and back again: A disulfide–thiolate interconversion process in a dinuclear copper complex is induced by chloride ions (see scheme). Within this compound, the coordinating copper atoms serve either as electron source or as electron sink and thus oscillate between the oxidation states +I and +II.
