LiOH has been found to be a very simple and selective catalyst for the rapid and mild synthesis of β-hydroxy sulfides and β-hydroxyl nitriles by ring opening of epoxides with aromatic, aliphatic, and heterocyclic thiols and trimethylsilyl cyanide at room temperature under solvent free conditions. All the reactions proceeded satisfactorily in short times and afforded the corresponding products in good to excellent yields with high regioselectivity and chemoselectivity under mild reaction conditions.

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
Humicola lanuginosa lipase-catalyzed enantioselective resolution of β-hydroxy sulfides: Versatile synthons for enantiopure β-hydroxy sulfoxides
Singh, Satwinder,Kumar, Subodh,Chimni, Swapandeep Singh
, p. 2457 - 2462 (2007/10/03)
Humicola lanuginosa lipase-catalyzed acylation of β-hydroxy sulfides provides both the (R)- and (S)-enantiomers in high enantiomeric purity. In two cases the resolved hydroxy sulfides were oxidized to give β-hydroxy sulfoxides in >99% e.e. The effect of substituents on enantioselectivity is discussed.

LnCl3 (Ln = Ce,Sm) and Eu(fod)3 act as Lewis-acid catalysts in stereo- and regioselective epoxide ring opening reactions with thiols under mild conditions in CH2Cl2.
Reaction kinetics of β-hydroxyalkyl sulfides with olefin α-oxides
Vints,Malievskii
, p. 394 - 395 (2007/10/05)
1. The reactions of olefin α-oxides with R β-hydroxyalkyl sulfides are equilibrium reactions. Some of the kinetic parameters of these reactions were determined. 2. An increase in the electron density on the sulfur atom facilitates the progress of the give
