AbstractA palladium complex of a dendrimer type ligand of aminoethylacrylamide immobilized onto the mesoporous channels of MCM-41 with magnetic core was prepared and characterized using various techniques such as XRD, TEM, BET, FT-IR, TGA, and VSM. The prepared nanostructured material was found as a magnetically recoverable catalyst for Heck reaction of aryl halides and vinylic C–H. The catalyst is easily recoverable with an external magnet and is reusable with different leaching amounts depending to loading of Pd. A hot filtration test was also performed and gave evidence that Palladium in heterogeneous samples can dissolve and then redeposit on the surface of the support material.

An N-heterocyclic carbene-based palladium complex was successfully immobilised on the inner surfaces of hollow silica nanospheres. The external surfaces of these spheres were functionalised with a corona-canopy to produce a Type I porous liquid. To confirm the successful immobilisation of the catalytic precursor, the porous liquid system was explored using the Heck reaction as a model reaction. This work demonstrated that homogeneous catalysts can be successfully immobilised within porous liquids in principle and that the approach used could be readily adapted for the immobilisation of other systems.
