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

Li GX, Wang B, Wang JM, Ding Y, Yan L, Suo JS

Wells-Dawson type Heteropolyacids (H6+nP2Mo18-nVnO62) (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 H7P2Mo17VO62 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 x 10(4) h(-1) of TOF.
