Magnesium chloride-catalyzed thiolysis of epoxides: Synthesis of β-hydroxy sulfides

A mild and convenient ring opening of epoxides with thiophenol and its derivatives takes place at room temperature in the presence of magnesium chloride as catalyst to afford the corresponding β-hydroxy sulfides along with minor amounts of 2-chlorocycloalkanols in good yields. When the crude reaction mixtures are treated with aqueous sodium hydroxide solution, pure 2-arlythiocycloalkanols are obtained in good yields.

A Change from Kinetic to Thermodynamic Control Enables trans-Selective Stereochemical Editing of Vicinal Diols

Here, we report the selective, catalytic isomerization of cis-1,2-diols to trans-diequatorial-1,2-diols. The method employs triphenylsilanethiol (Ph3SiSH) as a catalyst and proceeds under mild conditions in the presence of a photoredox catalyst and under

Method for catalyzing catalytic oxidation reaction of cyclopentene by vacancy silicon-tungsten heteropolyacid salt catalyst

The invention relates to a method for catalyzing a catalytic oxidation reaction of cyclopentene by utilizing a vacancy silicon-tungsten heteropolyacid salt catalyst. The invention aims to provide a process method for preparing glutaraldehyde and 1, 2-cyclopentanediol by carrying out catalytic oxidation on cyclopentene by using a two-vacancy silicon-tungsten heteropolyacid salt catalyst, which is small in environmental pollution, high in catalytic activity, high in yield and easy in recycling of the catalyst. According to the technical scheme, the method comprises the following steps of: (1) weighing cyclopentene, a heteropolyacid catalyst and 30% hydrogen peroxide according to a reaction molar ratio of 1: (0.0002-0.0020): (0.5-4.0), adding a quantitative reaction solvent, mixing well, controlling the temperature range to be 30-55 DEG C, reacting for 0.5-8 hours, and stirring until the reaction is finished; (2) carrying out a rectification process on a mixture generated by the reaction to obtain glutaraldehyde and 1, 2-cyclopentanediol; and (3) carrying out reduced pressure distillation on the reaction liquid to remove the solvent, and filtering, washing, vacuum-drying, collecting and recycling the vacancy silicon-tungsten heteropolyacid catalyst.
