Functional ionic liquids based on DABCO: Efficient catalysts for chemical fixation of CO <sub>2</sub> into cyclic carbonates
A series of basic functional ionic liquids were prepared from 1, 4-diazabicyclo [2.2.2] octane (DABCO) with various halogenated hydrocarbons, then these functional ionic liquids were used as catalysts for the chemical fixation of CO<sub>2</sub> into cyclic carbonates and the influence of the structure of the ionic liquids was investigated. The results showed that the N atom active center, types of anions and hydrogen bond of the catalyst play a key role in the cycloaddition reaction of CO<sub>2</sub> with epoxides to cyclic carbonates. Under mild reaction conditions (T = 100 °C, 1 atm CO<sub>2</sub>), the ionic liquid [DABCO-CH<sub>2</sub>CH<sub>2</sub>CH<sub>2</sub>OH] I showed the best catalytic effect, which has notable advantages such as high catalytic activity, eco-friendly, ease of work-up and convenient reuse.
