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