Cabrera, A. published the artcile1,3-Dioxolane formation with a montmorillonite-type clay catalyst, Safety of 2,2,4-Trimethyl-1,3-dioxolane, the publication is Journal of Molecular Catalysis (1992), 75(1), 101-7, database is CAplus.
The coupling reaction of oxiranes with carbonyl compounds to produce 1,3-dioxolanes was promoted by catalytic amounts of a bentonitic clay. The product yield was found to be dependent on the catalyst, the reaction temperature and the reagent concentrations Thus, ethylene oxide (I) reacted with MeCOMe in the presence of the clay to give 2,2-dimethyl-1,3-dioxolane in 96% yield. Reacting I with MeCO(CH2)2Me gave 2-methyl-2-propyl-1,3-dioxolane in 25% yield. A kinetic study performed with acetone and ethylene oxide showed a first-order dependence in both reagents. Other experiments made with different epoxides, carbonyl compounds and catalysts are also discussed.
