The pH dependence of thiolysis of 1,2-epoxides with thiophenol in water and the influence of a Lewis acid catalyst is investigated. InCl3 showed a very high efficiency in catalyzing this process at pH 4.0. The regloselectivity of the nucleophilic attack is markedly influenced going from pH 9.0 to pH 4.0. A one-pot procedure running solely in water to prepare trans-2-(phenylsulphinyl)cyclohexan-1-ol is reported starting from epoxycyclohexane, via thiolysis reaction and oxidation with t-butyl hydroperoxide.
