Abstract

Highly dispersed copper oxide on silica reveals to be aneffective acidic catalyst for the epoxide alcoholysis. Thecombination of acidic properties and hydrogenation activitywhen used in its reduced form makes the same catalyst anexcellent system for the one-pot one-step O-alkylation ofaromatic ketones and for the intramolecular cyclisation ofγ-unsaturated ketones into ethers.
