The authors developed a universal single-stage method of synthesis of acetylenic alcohol ethers, including allyl and propargyl. Conducting the synthesis in one preparative stage is due to the fact that etherification of acetylenic alcohol alcoholates by organyl halides takes place in the same apparatus without separation of the intermediate product, i. e. , the synthesis is actually reduced to successive treatment of ketone with acetylene (or vinylacetylene) and organyl halides. The yield of ethers is weakly dependent on the structure of the ketone and organyl halide radicals. In the case of propargyl chloride, the formation of dipropargyl ether is observed (yield of 5%), which indicates the possibility of partial hydrolysis of the halide.
