Heterogeneous alkenylation of aromatics under oxygen

A novel heterogeneous Pd/polymer catalyst containing co-catalytic functional groups catalyses the direct alkenylation of anisole with ethyl trans-cinnamate under oxygen. The properties of the polymeric catalyst were compared to other immobilised catalysts. The activity of the polymeric catalyst typically increased with temperature and oxygen pressure exhibiting the optimal activity up to 100 TO...

Catalyzed Schiff Base synthesis over Bifunctinalized Cobalt/Zinc-Incorporated Mesoporous Silica Nanoparticles under UV irradiation

A novel series of the Co/Zn-MSN catalysts with Si/Zn molar ratio of 10 and 1, 3, 5 and 7 wt% Cobalt (denoted by CZ-X-MSN) were synthesized using post-synthesis methods. The samples were characterized by XRD, SEM, FTIR, TEM and nitrogen sorption methods. With a constant Si/Zn ratio, the increase of cobalt species from 1 to 7 wt% led to decrease the catalysts surface area from 408 m2g-1 for CZ-1-...

Mesoporous Silica-Supported Amidozirconium-Catalyzed Carbonyl Hydroboration

The hydroboration of aldehydes and ketones using a silica-supported zirconium catalyst is reported. Reaction of Zr(NMe2)4 and mesoporous silica nanoparticles (MSN) provides the catalytic material Zr(NMe2)n@MSN. Exhaustive characterization of Zr(NMe2)n@MSN with solid-state (SS)NMR and infrared spectroscopy, as well as through reactivity studies, suggests its surface structure is primarily ≡SiOZr...
