Yield:-

Reaction Conditions:

with zirconia pillared zirconium phosphate ZrO₂-ZrP-a-150 in toluene at 80; for 4 h;Reagent/catalyst;

Steps:

Catalytic tests

General procedure: The Prins condensation of β-pinene with paraformaldehyde was carried out in a three-necked flask equipped with a condenser. Typically, 50 mg catalyst, 1 mmol (0.136 g) β-pinene, 2 mmol (0.06 g) paraformaldehyde and 5 ml toluene were added with magnetic stirring at 80 °C for 4 h. The products were analyzed by a gas chromatograph equipped with a SE-30 capillary column (30 m × 0.25 mm × 0.3 μm).
