Efficient Heterogeneous Palladium Catalysts in Oxidative Cascade Reactions

Heterogeneous catalysts for carbene insertion reactions

Copper catalysts supported on silica or silica-alumina are used to promote the insertion of carbenes, coming from methyl phenyldiazoacetate and ethyl diazoacetate, into one C-H bond of THF, constituting the first example of this reaction promoted by a purely inorganic catalyst. Cu/SiO2-Al2O3 leads to better results, regarding yield and catalyst recovery, than with Cu/SiO2. With the former catal...

Mild synthesis of Mesoporous silica supported ruthenium nanoparticles as heterogeneous catalysts in oxidative Wittig coupling reactions

Porous organic cage stabilised palladium nanoparticles: efficient heterogeneous catalysts for carbonylation reaction of aryl halides.

Porous organic cage stabilised palladium nanoparticles were successfully prepared using methanol as a mild reductant. The as-prepared porous composite materials show high catalytic activity for the carbonylation reaction of aryl halides under mild conditions.

Bimetallic Catalysts Containing Gold and Palladium for Environmentally Important Reactions

Supported bimetallic nanoparticles (SBN) are extensively used as efficient redox catalysts.
