Abstract

Various types of oxiranes react with acetone in the presence of catalytic amounts of ammonium decatungstocerate (IV) icosahydrate, (NH4) 8[CeW10O36]. 20H2O to give 1,3-dioxolanes. The 1,3-dioxonation of cyclohexane oxide with acetone using catalytic amounts of various polyoxometalate complexes (0.04M) was also examined. Ammonium decatungstocerate icosahydrate was prepared using Peacock's procedure. It was reported that (NH4)8[CeW 10O36]. 20 H2O can be used as an effective catalyst for the conversion of oxiranes to thiiranes.
