Abstract

Abstract: Chromans 3 and o-isopentenylphenols 4 are synthesized in satisfactory to good yields and selectivities by the reaction of phenols and isoprene in the presence of the commercially available acid faujasite zeolite HSZ-360. Key words: heterogeneous catalysis, zeolite HSZ-360, isoprene, chromans, ortho-isopentenylphenols
