Abstract
A novel reusable Lewis acid catalyst has been prepared by the heterogenizat ion of a Lewis acid/tetrapropylammonium adduct; anchoring of tin chloride o n quaternary ammonium chloride functionalized MCM-41 yielded a catalyst wit h higher activity compared to the corresponding silica analogue in terms of turnover rates and product yield in the Prins condensation of isobutene an d formaldehyde to isoprenol.
