Abstract

Ligand scrambling reactions in some cyano(selenone)gold(I) complexes, [>C=Se-Au-CN] to form [(>C=Se)₂Au]⁺ and [Au(CN)₂]^- species have been studied in DMSO using ¹³C and ¹⁵N NMR spectroscopy. As a result of the scrambling reaction, two sharp resonances are observed both for the carbon and nitrogen of CN^- in ¹³C and ¹⁵N NMR, respectively, corresponding to the two equilibrium components, [>C=Se-Au-CN] and [Au(CN)₂]^-. Equilibrium constants (K_eq) were determined for the scrambling equilibria by integrating the CN^- resonances in the ¹³C NMR recorded at 298 K.
