Abstract: Zirconium-containing catalysts were found to be active in the Meerwein-Ponndorf-Verley (MPV) reduction of citral. Good activity and selectivity to the reduced alcohol, geraniol and nerol, were observed over hydrous zirconia and zirconium 1-propoxide supported on silica. In particular, hydrous zirconia calcined at temperatures below 300°C was highly active. Hydrous zirconia catalysts modified by NaOH, NH4F, PO 4 3- and SO4 2- had lower activity. Surface hydroxyl groups are postulated to be involved in ligand exchange with the reductant, 2-propanol. Zr-zeolite beta showed high activity, but poorer selectivity than the other two samples, due to subsequent dehydration of the product formed. For all catalysts, the trans-isomer of citral was preferentially reduced over the cis-isomer. © 2004 Elsevier B.V. All rights reserved.
