Efficient and highly-selective cycloaddition of epoxides with carbonyl compound over Wells–Dawson type heteropolyacids

Abstract

Wells–Dawson type Heteropolyacids (H 6+ n P 2Mo 18− n V n O 62) ( n = 0–2, 4) have proved to be efficient heterogeneous catalysts for the reaction of epoxides with carbonyl compounds to form 1,3-dioxolane derivatives. Especially, when H 7P 2Mo 17VO 62 was used to catalyze the reaction between acetone and epoxypropane, the selectivity to 1,3-dioxolane reached to 93.3% with nearly complete conversion of epoxide and 1.1 × 10 4 h −1 of TOF.
