The Prins addition between rosin resin acids and formaldehyde catalyzed by p-toluenesulfonic acid was studied in detail.

Study on the Prins Reaction of Styrene with Formalin Catalyzed by Tungstogermanic Acid;

4-Chloro-6-phenyl-2-(2-oxopropyl)tetrahydropyran was obtained unexpectedly by the Prins reaction of 4-methyl-1,8-nonadiene-4,6-diol and benzaldehyde in the presence of indium trichloride in methylene chloride at room temperature.

The paper introduced the research development of Prins reaction catalysts,summarizing application of various catalysts form on Prins reaction,emphasising on discussing effects of selectivity and specificity on zeolite catalysts and ionic liquids,and pointed out that compounding use of new catalyst will be the direction and hotspot for the future research.

A Prins condensation of formaldehyde with alkene for synthesis of 1,3-dioxane and its derivatives catalyzed by a series of functional acid ionic liquids has been investigated.
