摘要：

Conversion of epoxides to thiiranes with ammonium thiocyanate or thiourea in the presence of poly(4-vinyl pyridine)-Ce(OTf)(4) as catalyst and under non-aqueous condition is reported. Stereospecific conversion of R-(+)-styrene oxide to S-(-)-styrene sulfide was achieved in high optical purity. The polymer can be easily reloaded.
