Fund Project: The authors are thankful to the Shahid Chamran University Research Council for partial financial support of this work.

For the first time,metal hydrogen sulfates and phosphates/silica gel have been studied as efficient and powerful solid acid catalysts in the ring opening of epoxides with thiocyanate anion.The most significant result was obtained by Al(HSO₄)₃/SiO₂ which afforded the corresponding β-hydroxy thiocyanates under mild reaction conditions and in very short reaction times.The cheapness,availability of the catalyst,ease of procedure and work-up make this method attractive for the organic synthesis.
