mmol, 0.1518 g). The reaction vessel was sealed and the pressure of
CO2 was kept at 1 MPa. The test-tube was placed in a water bath of 30
oC and was allowed to stir overnight. After the reaction, the reactor was
placed in ice water for 20 minutes and CO2 was vented slowly. Then
dichloromethane (5 mL) was added in the reaction mixture. After
removing precipitate by centrifuging, the reaction mixture was washed
with water, dried over Na2SO4 and filtered. The solvent was removed
under vacuum to afford M as a colorless oil.

Conclusions
In conclusion, using AgCl/[Bmim][OAc] as catalyst and
solvent, a series of unsymmetrical organic carbonates can be
synthesized efficiently by the reaction of CO2 with propargylic
alcohols and primary alcohols under ambient conditions. The
yields of the desired products can approach 100%, and the
catalyst system can be easily recovered and reused. The
catalyst system not only combines the advantages of
homogenous and heterogeneous catalysts, but also the easy
separation of catalyst. We believe that this greener route has
great potential application for producing unsymmetrical organic
carbonates using CO2 as a feedstock because of ambient
reaction condition, very high yield, and efficient and reusable
catalyst system.

General procedure for the preparation of unsymmetrical organic
carbonates: as an example, the procedure using 1a and 2a as the
substrates are described, and those for other substrates are similar. In a
typical experiment, 1a (1.5 mmol, 0.1262 g), 2a (1.5 mmol, 0.0484 g),
[Bmim][OAc] (1.5 mmol, 0.2974 g) and AgCl (0.3 mmol, 0.0431 g) were
loaded into a 22 mL stainless-steel batch reactor equipped with a
magnetic stirrer. The air in the reactor was removed by blowing CO2 into
the reactor. Then the pressure of CO2 was kept at 0.1 MPa using a
balloon with CO2. The reactor was placed in a water bath of 30 oC and
the reaction mixture was stirred for a desired time. After the reaction, the
product was extracted by diethyl ether and the solvent was removed
under vacuum to afford the desired carbonate 3a as a colorless oil. After
5 times of recycle, the IL in the catalyst system was extracted by H2O,
and then was characterized by 1H and 13C NMR after removing H2O
under vacuum. The white precipitation that was insoluble in HNO3
solution was AgCl.
