Selectivity enhancement of silica-supported sulfonic acid catalysts in water by coating of ionic liquid

Coating of silica-supported sulfonic acid catalysts with hydrophobic ionic liquid leads to a significant improvement of catalyst selectivity. Many organic reactions, including Prins cyclization, cycloaddition of epoxide to aldehyde, and dehydrative etherification of secondary benzyl alcohols, proceed well in formalin or pure water. In particular, tandem dehydration/Prins cyclization reactions of tertiary and secondary alcohols with formaldehyde were developed for the first time.

Fragmentation of Cyclic Carboxonium Ions, IV. - Synthesis of β-Oxa-γ, δ-enones

The proton-catalyzed fragmentation of 4-methylene-1,3-dioxolanes 2 by weak acids (pK > 4.3) or weak acidic ion exchangers leads in good yields to β-oxa-γ, δ-enones 5 which are thus easily and generally available for the first time.
