Task-specific ionic liquid and CO2-cocatalysed efficient hydration of propargylic alcohols to α-hydroxy ketones† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c5sc00040h Click here for additional data file.
The hydration of propargylic alcohols is a green route to synthesize a-hydroxy ketones. Herein a CO2reactive ionic liquid (IL), [Bu4P][Im], was found to display high performance for catalyzing the hydration of propargylic alcohols in the presence of atmospheric CO2, and a series of propargylic alcohols could be converted into the corresponding a-hydroxy ketones in good to excellent yields. In t...
متن کاملApplication of multipurpose dimethyl formamide-like task specific ionic liquid as a recyclable reagent for direct iodination of alcohols
A direct and an efficient conversion of a wide range of primary, secondary even tertiary alcohols to the corresponding iodides have been achieved under ionic liquid conditions. The method involves preparation of ionic liquid-based iminium chloride intermediate from DMF-like ionic liquid then stirring it with alcohol in present of sodium iodide. The higher yields of alkyl iodides were obtained w...
متن کاملEfficient and reversible CO2 capture by amine functionalized-silica gel confined task-specific ionic liquid system
Simple, efficient and practical CO2 capture method is reported using task-specific ionic liquid (IL) supported onto the amine-functionalized silica gel. The results have been shown that both the capacity and rate of the CO2 absorption notably increase in the supported IL/molecular sieve 4 Å system in comparison of homogeneous IL. Additionally, it has shown that the prepared material is capable ...
