Synthesis of 14-Oxabicycloclo[10,3,0]-2-Pentadecene with Strongly Acidic Cation Exchange Resins as Catalysts

The title compound was synthesized by the reaction of cyclododecene with pafaformaldehyde using three kind's of strongly acidic cation exchange resins, i.e., polystyrene, phenol formaldehyde and perfluorinated resin sulfonic acid, as catalysts. The catalytic efficiency of the resin acids, described above, was examined and the results obtained were compared with that of benzene suifonic acid and toluene sulfonic acid. The influence of the pore size, bead size and reaction conditions employed for the catalytic behaviour of the polystyrene sulfonic acid was studied.From the results of the experiments, It was shown that the perfluo-riflated resin sulfonic acid (Nafion Hform) and macroporous cross-linked" polystyrene sulfonic acid (DVB 10%, average pore radius 3.9×10²Å, specific surface area 20m³/g) possess satisfactory catalytic activity.
