The direct substitution of alcohols and β-dicarbonyl compounds was catalyzed with FeCl3 under solvent-free conditions. The catalyst loading could be decreased to 0.01 mol% in high activities.

Abstract

The direct substitution of alcohols and β-dicarbonyl compounds was catalyzed with FeCl3 under solvent-free conditions. The catalyst loading could be decreased to 0.01 mol% at high activities. It was shown that the reaction proceeded in two steps via the etherification of the alcohols. This method provided an easy and practical procedure for C[BOND]C bond formation.Copyright © 2007 John Wiley & Sons, Ltd.
