REACTION OF 1-PROPYN-3-OL WITH ALCOHOLS

The reaction of propargyl alcohol with primary alcohols in the presence of metal complex catalysts leads to 2,5-dialkoxy-2,5-dimethyl-1,4-dioxanes.In contrast to primary alcohols, condensation to form 3-alkoxy- or 3-aryloxypyronines is the first step of the reaction of trimethyl-, dimethylethyl-, and triphenylcarbinols with propargyl alcohol.In the case of alkylcarbinols, these pyronines undergo hydration of the triple bond and cleavage of alkoxyacetones.One of the products of the reaction of propargyl alcohol with trimethyl- and dimethylcarbinols is 2,5-di(2-propynoxy)-2,5-dimethyl-1,4-dioxane.The same product was isolated upon heating propargyl alcohol in ether in the presence of HgO + (C2H5)2O.BF3.
