Disulphide bond cleavage in a pyridine-containing disulphide–copper(II) system under aerobic conditions. X-Ray crystal structure analysis of the product, diaquabis{µ-2-[(2-pyridymethyl)-amino]ethylsulphinato-O}dicopper(II) dichloride

Abstract

The diaulphide bond in a pyridine-containing disulphide was cleavage in the presence of copper(II) and dioxygen to give the copper(II) complex of the corresponding sulphinate, whose X-ray crystal structure analysis has disclosed a dimeric structure with the sulphinate oxygen atom bridging the copper(II) ions in a square-pyramidal environment.
