GRAPHICAL ABSTRACT

ABSTRACT

Solvent-free conversion of various epoxides to the corresponding thiiranes was carried out successfully with alumina-immobilized thiourea at room temperature. The reactions were completed within 2–9 min to give thiiranes with 83–98% yields. The utilized alumina can be reused for several times without losing its activity.
