Catalytic reaction of 3-phenyl-2-propyn-1-ol with alcohols (in Russian)
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-BF/sub 3/ O(C/sub 2/H/sub 5/)/sub 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 saturated alcohol 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.
