A highly efficient and selective carbon-carbon double bond cleavage of olefins, chalcones and also oxidation of sulfides involving molecular oxygen is achieved using K10-montmorillonite clay-supported ceric ammonium nitrate (CAN) in methanol medium. The catalyst is recycled without any loss in activity and selectivity. A suitable mechanism wherein all the three species are assembled within the clay...
Nickel nanoparticles are prepared in the interlamellar spaces of K10-Montmorillonite clay by chemical reduction at moderate temperatures. These clay entrapped nickel nanoparticles are characterized by UV–vis, powder XRD, EDX and HRTEM studies. The resultant ecofriendly supramolecular assembly with nickel content (2.84wt%) has good catalytic efficiency in hydrogenation of alkenes and alkynes with hydrazine...
