    An efficient synthesis of β-azido alcohols and β-hydroxy thiocyanates has been achieved by ring opening of epoxides using 1,1'-bis-methyl-3, 3-methylene-bisimidazolium dichloride as a phase transfer catalyst at room temperature in water. The reaction is regioselective and afforded the corresponding products in moderate to excellent yields.

The results can be discussed in terms of a four-step mechanism (Scheme 2): 1) formation of a complex between catalyst and NH4SCN, 2) release of SCN− from the complex, 3) reaction of the released SCN− at the sterically

    a stable phosphine-free reagent for the conversion of alcohols into alkyl thiocyanates and epoxides into 2-hydroxythiocyanates. The reactions seem to proceed via in situ generation of electrophilic sulfur species by reaction of NH4SCN and TABCO. This combined reagent worked well with both alcohols and epoxides in acetonitrile solvent and under solvent-free conditions. GRAPHICAL ABSTRACT
