Spectroscopic Evidence for Ligand Substitution Reactions at the Solid-Liquid Interface of a Sub-micrometer Gold(I) Carbene Complex.

Colloidal coordination compounds in the sub-micrometer range were synthesized from a chloro gold(I) carbene complex via the anti-solvent procedure and stabilized by a surfactant shell of Tween 20. This compound was successfully applied as model system to monitor heterogeneous multiphase ligand substitution reactions at the solid-liquid interface.
