چکیده
Density functional theory calculations and 2D 1H-13C HETCOR solid state NMR spectroscopy prove that CO2 can be used to probe, by its own reactivity, different types of N-donor surface ligands on SBA15-supported Zr(IV) hydrides: [≡(Si-O-)(≡Si-N=)[Zr]H] and [≡(Si-NH-)(≡Si-X-)[Zr]H2] (X=O or NH). Moreover, [≡(Si–O-)(≡Si-N=)[Zr]H] activates CO2 more efficiently than the other complexes and leads to the formation of a carbimato Zr formate.

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...

متن کاملFrom Thioxo Cluster to Dithio Cluster: Exploring the Chemistry of Polynuclear Zirconium Complexes with S,O and S,S Ligands
Three different zirconium thio and oxothio clusters, characterized by different coordination modes of dithioacetate and/or monothioacetate ligands, were obtained by the reaction of monothioacetic acid with zirconium n-butoxide, Zr(O(n)Bu)4, in different experimental conditions. In particular, we isolated the three polynuclear Zr3(μ3-SSSCCH3)2(SSCCH3)6·2(n)BuOH (Zr3), Zr4(μ3-O)2(μ-η(1)-SOCCH3)2(...
