A new Ag 3 PO 4 @MOF-5 catalyst has been synthesized and successfully applied in the green synthesis of a library of indenoquinolinediones via one-pot, multi-component reaction of aldehyde, indanedione and enaminone under solvent-free conditions at room temperature. The catalyst was characterized using various spectroscopic techniques and elemental analysis. The catalyst can be easily separated and exhibits significant recyclability, with insignificant loss of activity after four consecutive runs. The protocol presented has advantages like green reaction conditions, high yield of products, no need for column chromatography and good recyclability.

Sulfonic acid functionalized metal–organic framework (S-IRMOF-3) as an efficient heterogeneous catalyst has been synthesized and employed for sustainable approach towards the synthesis of acrylonitriles in high yield and shorter reaction time period.

Silica modified imidazolium based halometallic ionic liquids, [smim][MCl4] and [smim][FeCl4]−@Nd2O3 were synthesized for the evaluation of acidic and catalytic properties.

A novel mesostructured catalyst sulphated alumina tungstic acid (SATA) has been prepared by an easy route.
