Abstract
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(HSO 4) 3/SiO 2 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.
