Transfer hydrogenation of carbonyl compounds and carbon–carbon multiple bonds by zeolite supported Cu nanoparticles

Efficient reduction of carbonyl compounds and C–C multiple bonds to the corresponding reduced products with 2-propanol as a green reducing agent is achieved by highly active copper nanoparticles supported on a zeolite framework. These nanoparticles are stable in a zeolite framework and are recycled with good catalytic activity in the absence of base. The synthesized zeolite supported Cu nanoparticles were characterized using UV-DRS, XRD, XPS and HR-TEM.
