Various types of hydroxyacetophenones are efficiently converted into the corresponding ethylene acetals in the presence of ethane-1,2-diol, triisopropyl orthoformate, and a catalytic amount of cerium(III) trifluoromethanesulfonate under mild reaction conditions. The homologous trimethylene acetals can be also prepared in the same way. Georg Thieme Verlag Stuttgart.

The titanium cation-exchanged montmorillonite efficiently catalyzed the selective acetalization of various carbonyl compounds as a recyclable solid acid. This heterogeneous catalyst has an advantage of a strikingly simple workup procedure over conventional homogeneous acids.
THE RELATIVE REACTIVITY OF 2-METHYL-1,3-DIOXOLANE IN RADICAL REACTION WITH UNSATURATED COMPOUNDS

The reactivity of 2-methyl-1,3-dioxolan-2-yl radicals toward α-olefins containing substituents with various polarities was studied.There is a substantial increase in the relative addition rate constant in the series consisting of vinyl butyl ether, 1-hexene, vinyl acetate, trimethylvinylsilane, methyl acrylate, and acrylonitrile.This indicates that the 2-methyl-1,3-dioxolan-2-yl radicals have clearly defined nucleophilic character.
