The activity of copper-on-silica gel catalysts prepared by ion-exchange in the double bond migration of alkenes has been studied in poisoning experiments, and by temperature-programmed desorption and IR spectroscopy. The active sites are protonic centres generated during the activation of the catalysts, together with Cu(I) ions formed as a result of the incomplete reduction of ion-exchanged copper species, inducing an ionic-type isomerization.
