| Popis: | Nano-silica supported ionic liquids composed of alkyl carbon chain and transition metal chlorides anions have been prepared and successfully applied as a heterogeneous catalyst in the direct aldehyde C-H activation. Catalytic results indicated that nano-SiO2 supported ionic liquid consisting C12 alkyl carbon chain and CoCl3 anion nano-SiO2@CoCl3-C12IL showed excellent catalytic properties with good to excellent yields towards the desired aryl ketones. The excellent recyclability of the supported catalyst, mild reaction conditions, low catalyst loading, and operational simplicity are the important features of this methodology. |
