::-)Hi,
Rhodium Archieve:"Piperonal and Safrole from Vanillin and Eugenol"
ich weiß das es mit Aluminiumiodid Katalysator im Rhodium Archieve beschrieben ist.:
Eugenol Demethylation with AlI3
Summary: Reflux aluminium powder with iodine in benzene or cyclohexane for 90 min to produce AlI3. Add equimolar amounts of EUGENOL, 0.25 eqv PTC (tetrabutylammonium iodide, chloride may also work), reflux for 20 min, and isolate the protocatechupropene.
