• Aliphatic aldehydes undergo the acyloin condensation in the presence of this catalyst and mild base. For example (butyraldehyde to butyroin), see: Org. Synth. Coll., 7, 95 (1990).
• The same system is effective in catalyzing the addition of aldehydes to electron-deficient alkenes, including ɑ?-unsaturated ketones, esters and nitriles (Stetter reaction), providing a non-toxic alternative to cyanide in these reactions; e.g. in the synthesis of dihydrojasmone: Org.
