Conversion of epoxides to thiiranes with thiourea or ammonium thiocyanate catalyzed with poly(4-vinyl pyridine)-Ce(OTf)4

Article abstract of DOI:10.1080/00397919908085959

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.
