Abstract
The structure of Stang’s reagent [PhI(CN)][OTf] is confirmed by X-ray crystallography and is determined to be best described as an ion-pair in organic solution. It is found to be a strong Lewis acid, but reaction with pyridine ligands gives [Pyr-CN][OTf] salts via redox and represents the first path to a new derivative of the CDAP reagent widely used as an activation agent for polysaccharides.
