Molybdenum containing surface complex for olefin epoxidation
Silica-supported molybdenum surface complexes were prepared by the reaction between (N=)Mo(OtBu)3 and silica via displacement of the tert-butoxy ligands for siloxyls from the silica surface. The structure of the surface molybdenum complexes was well defined by in-situ FT-IR, elemental analysis, H NMR and C CP/MAS NMR techniques. The surface complexes could undergo alcoholysis reaction with CD3O...
متن کاملA metal-organic framework material that functions as an enantioselective catalyst for olefin epoxidation.
A new microporous metal-organic framework compound featuring chiral (salen)Mn struts is highly effective as an asymmetric catalyst for olefin epoxidation, yielding enantiomeric excesses that rival those of the free molecular analogue. Framework confinement of the manganese salen entity enhances catalyst stability, imparts substrate size selectivity, and permits catalyst separation and reuse.
متن کاملMolybdenum-Schiff Base Complex Immobilized on Magnetite Nanoparticles as a Reusable Epoxidation Catalyst
The surface of magnetite nanoparticles as nano-sized solid support was modified with a molybdenum-Schiff base complex to prepare an easily separable heterogeneous catalyst for the epoxidation of olefins. Characterization techniques such as Fourier transform infrared and inductively coupled plasma optical emission spectroscopies, X-ray diffraction, vibrating sample magnetometry, scanning, an...
متن کاملDiamido Complexes of Titanium and Zirconium as Catalyst Precursors for Ethylene Polymerization
A series of 8 new complexes of titanium and zirconium with diamido ligands bearing an ethylene and propylene bridge between the two amido groups were synthesized and tested for ethylene polymerization. Titanium complexes bearing an ethylene bridge between the two amido groups showed higher activities than the derivatives with a propylene bridge. In the case of the zirconium complexes, the p...
متن کاملDiphenylamido Precursors to Bisalkoxide Molybdenum Olefin Metathesis Catalysts.
We have found that Mo(NAr)(CHR')(NPh(2))(2) (R' = t-Bu or CMe(2)Ph) and Mo(NAr')(CHCMe(2)Ph)(NPh(2))(2) (Ar = 2,6-i-Pr(2)C(6)H(3); Ar' = 2,6-Me(2)C(6)H(3)) can be prepared through addition of two equivalents of LiNPh(2) to Mo(NR″)(CHR')(OTf)(2)(dme) species (R″ = Ar or Ar' dme = 1,2-dimethoxyethane), although yields are low. A high yield route consists of addition of LiNPh(2) to bishexafluro-t-...
