Iodine and iodine supported on polyvinylpyrrolidone (betadine) have been used as catalysts for ring opening of epoxides and as reagent for ring-opening dimerization of thiiranes in alcohols, water, and acetic acid. The reactions occur with high regio-, chemo-, and stereoselectivity. The reaction of R-(+)-styrene oxide with I2 supported on PVP in methanol was found to be very stereospecific and the product was isolated in 93% ee.

Silica gel functionalized by aminopropyl group was prepared. Iodine was then supported on this inorganic polymer and used as a stable and efficient heterogeneous catalyst for nucleophilic ring opening reactions of epoxides and episulfides in different nucleophilic solvents such as alcohols, water and acetic acid.
Efficient, mild, and regioselective conversion of thiiranes to alkoxy and acetoxy disulphides and dithianes with Ce(IV) based oxidants
Iranpoor,Owji
, p. 149 - 154 (2007/10/02)
Alcoholysis of thiiranes with primary and secondary alcohols followed by the formation of their corresponding alkoxy-disulphides is performed efficiently in one step with different Ce(IV) salts, such as ceric ammonium nitrate (CAN), ceric pyridinium nitra
Regioselective Alcoholysis and Conversion of Thiiranes to Alkoxy-Disulfides with 2,3-Dichloro-5,6-dicyano-p-benzoquinone (DDQ)
Iranpoor, N.,Owji, J.
, p. 1047 - 1053 (2007/10/02)
Alcoholysis of thiiranes followed by conversion to their corresponding alkoxy-disulfides with 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) is performed in one step.The reactions occur under neutral conditions with high regioselectivity.Alkoxy-disulfides are obtained in 30-90percent yields.
