Oxiranes undergo rapid ring-opening reaction with a range of thioamides and amines to afford the corresponding β-amino alcohol derivatives. The reactions were carried out using glycerine and cerium(III) chloride as a recyclable reaction medium. All the reactions were carried out at room temperature and the products were obtained in excellent yields.

N-Fluorobenzenaminium tetrafluoroborate generated in situ by aniline and Selectfluor as a reusable catalyst for the ring opening of epoxides with amines under microwave irradiation
The ringopening of epoxides with aromatic and aliphatic amines was carried out under solvent free conditions using N-fluorobenzenaminium tetrafluoroborate (2 mol%) generated in situ by the reaction of aniline and Selectfluor as a catalyst with microwave irradiation. Excellent yields of β-amino alcohols were obtained. The catalyst also results in the retention of the stereochemistry for the ring opening
