It has been known that when α-ethynyl-tert-alcohol is reacted with carbon dioxide in the presence of a copper salt and a trialkylamine, α-methylene-cyclic carbonate is obtained (German Patent No. 1098953 and 1145632 specification). The reaction in this case is expressed by the following formula.

(In the above formula, R 1 and R 2 represent an alkyl group.) [Purpose] The present inventors have conducted various studies on the reaction between alcohol having an ethynyl group (acetylenic alcohol) and carbon dioxide. However, when carbon dioxide is reacted with propargyl alcohol in the presence of a lower alkyl alcohol having 1 to 3 carbon atoms, a carbonate having a chain-like keto group is surprisingly obtained, unlike the conventional method. I discovered that.

The reaction is carried out in the presence of a ruthenium catalyst, and the reaction conditions include carbon dioxide under pressure and a relatively low temperature, preferably around 0°C to room temperature, in order to suppress the polymerization of the raw material propargyl alcohol. will be adopted. As the ruthenium catalyst, its halide or carbonyl complex is used, and it is desirable to use an organic base such as a tertiary amine as a co-catalyst. As the pressurization of carbon dioxide, a pressure of about 10 to 50 atmospheres is usually employed. The ratio of lower alkyl alcohol used is 1 to 10 mol, preferably 50 mol per mol of propargyl alcohol.
The proportion is ~10 mol.
