An efficient and rapid procedure for ring opening reaction of various epoxides with phenol and thiophenol derivatives was developed. The procedure can be obtained at room temperature under solvent-free condition in presence of (C4H12N2)2[BiCl6] Cl·H2O (1 mol %). This catalyst can be reused several times without significant loss of activity.

2,4,6-Trichloro-1,3,5-triazine-catalyzed convenient and efficient ring opening of epoxides with thiols under solvent-free conditions is described. Short reaction time, mild reaction conditions, inexpensive and readily available catalyst, and excellent yie
Highly regioselective ring opening of epoxides with thiols catalyzed by SbCl3 under solvent-free conditions

experimental part, p. 3018 - 3022 (2009/10/02)
The ring-opening reaction of epoxides with thiols by SbCl3 supported on Kieselguhr under solvent-free conditions, afforded high yields of β-hydroxy sulfides. Nucleophilic attack of the thiols occurs regioselectively at the less hindered side of the epoxid
Regioselective ring-opening reactions of 1,2-epoxides with thiols and arylselenols directly promoted by [Bmim]BF4

supporting information; experimental part, p. 6471 - 6474 (2009/04/06)
Regioselective ring-opening reactions of 1,2-epoxides with ArSH and ArSeH promoted by ionic liquid [Bmim]BF4 were investigated. A variety of β-hydroxy selenides and β-hydroxy sulfides were obtained in excellent yields (81-99%) with good regiose

, p. 1199 - 1205 (2007/10/03)
Optically active (R)- and (S)-1-substituted-3-(arylthio)propan-2-ols have been prepared in the reaction of the appropriate 2-(arylthiomethyl)oxiranes with chloride and azide anions followed by a lipase-catalyzed transesterification. The effects of the enzyme preparation as well as of the reaction conditions have been compared in terms of the enantiomeric excess of the obtained acetate and unreacted alcohol.
