pported thiocyanate ion, [P4-VP]SCN, is introduced as recyclable polymeric reagent for the efficient and regioselectiveconversion of epoxides to thiocyanohydrins in the presence of cross-linked poly(4-vinylpyridine)-supported sulfuric acid, [P4-VP]H2SO4, as a solid proton source and as catalystunder solvent-free conditions. The ring-opening reaction of epoxides take place very fast under solvent-free
