Cyclic ketals - 2,5-dimethyl-2,5-bis(4-penten-2-ynyloxy)-1,4-dioxane and 2,5-dimethyl-2,5-bis(3-phenyl-2-propynyloxy)-1,4-dioxane - were isolated in the reaction of propargyl alcohol with vinyl- and phenylethynylcarbinols in the presence of HgO-BF3.O(C2H5)2 catalytic system.

The cyclic ketal 2,5-dimethyl-2,5-bis(3-phenyl-2-propynyloxy)-1,4-dioxane was obtained by the reaction of 3-phenyl-2-propyn-1-ol with propargyl alcohol in the presence of the HgO-BF3*O(C2H5)2 catalytic system.The transformation of 3-phenyl-2-propyn-1-ol and its ethers in methanol and ethanol by the action of the above-mentioned catalytic system leads to 1-phenyl-3-alkoxy-1-propanone, 1-phenyl-1,1,3-trialkoxypropane, and 1-phenyl-2-propen-1-one.The intermediate organomercury compound, which is the product from regioselective addition of mercuric oxide and the saturatedalcohol at the triple bond, was isolated.Its protodemercuration led to the above-mentioned linear products.The formation of the cyclic ketal is presumably due to the preferred formation of mercury bis-hydroxypropargylide.x
