Novel condensation of ketones with homoallyl alcohols catalyzed by Hg(OTf)2 has been developed, generating a 6-membered ring ether alcohol, bisether, and olefins. The reaction is initiated by hemiacetal formation, and cyclization of the resulting oxonium action provides the 6-membered ring carbocation as a common intermediate. Thus, it is a catalytic Prins-type condensation of non-activated hormoallyl alcohols and ordinary ketones.

3-Methyl-3-buten-1-ol reacts with various aldehydes and ketones on silica gel and Al2O3 surfaces in the absence of solvents and conventional catalysts for this reaction to form derivatives of di- and tetrahydropyrans.

4-Methylenetetrahydropyran undergoes isomerization to 4-methyl-5,6-dihydropyran in the presence of sodium on aluminum oxide.Both pyrans are converted to a vinyl ether, viz., 4-methyl-2,3-dihydropyran, under the influence of iron pentacarbonyl.
