were investigated for the synthesis of 1, 3-dioxane in dichloromethane under reflux and at ambient temperature. The Prinscyclization of 3-butene-1-ol with aromatic aldehydes yielded 2,4- disubstituted tetrahydropyran ether 4 as single product in dichloromethane using both PANI-TsOH and PANI-FeCL3 as reusable acid catalysts. Both catalysts were investigated for the synthesis of 1, 3-dioxane in dichloromethane

Silica-supported p-toluene sulfonic acid is found to be an excellent catalyst for the Prins reaction to produce 1,3-dioxanes in good yields from olefins and aliphatic aldehydes in dichloromethane at room temperature and solventless microwave irradiation within a short reaction time.

formaldehyde (FCHO)) under different reaction conditions to obtain 1,3-dioxanes, which are widely used as solvents or intermediates in organic synthesis. Based on the nature of catalysts used under different reaction conditions, a reasonable plausible reaction mechanism for the Prins cyclization of SE with PFCHO is proposed. Notably, it can be seen from the catalytic results of all catalysts that the W-ZnAlMCM-41(75)
