Metal alkoxides: Models for metal oxides: Alkoxide ligands in early transition metal organometallic chemistry [PDF]

open access: green, 1990
An effort was made to compare and contrast the reactivity of trialkylsiloxide vs tert-butoxide supported dinuclear centers, and an initiative aimed at studying the syntheses of polynuclear hydridoalkoxides and their reactions has been implemented.

COORDINATION COMPLEXES OF METAL ALKOXIDES: PART II. METAL ALKOXIDE – ETHYLENEDIAMINE COMPLEXES [PDF]

open access: bronzeCanadian Journal of Chemistry, 1962
Some complexes of titanium isopropoxide, titanium ethoxide, aluminum isopropoxide, tantalum isopropoxide, and zirconium isopropoxide with ethylenediamine (en) are described. Two complexes of titanium isopropoxide with ethylenediamine, i.e. Ti(OPri)4,en and Ti2(OPri)8,en, were established by cryoscopic, X-ray powder photograph, and phase rule studies ...

An unusual chiral-at-metal mechanism for BINOL-metal asymmetric catalysis [PDF]

open access: yesNature Communications
Chiral binaphthols (BINOL)-metal combinations serve as powerful catalysts in asymmetric synthesis. Their chiral induction mode, however, typically relies on multifarious non-covalent interactions between the substrate and the BINOL ligand.

Heterobimetallic Uranium(V)-Alkali Metal Alkoxides: Expanding the Chemistry of f-Block Elements [PDF]

open access: yesMolecules
Heterobimetallic uranium(V) alkoxides incorporating monovalent alkali metal counterions display remarkable structural versatility, dictated by the steric demands of the alkoxide ligands and the ionic radius of the alkali metal.

Alkoxide-based precursors for direct drawing of metal oxide micro- and nanofibres

open access: greenScience and Technology of Advanced Materials, 2011
The invention of electrospinning has solved the problem of producing micro- and nanoscaled metal oxide fibres in bulk quantities. However, until now no methods have been available for preparing a single nanofibre of a metal oxide.

METAL OXIDE ALKOXIDE POLYMERS: PART IV. THE HYDROLYSIS OF SOME TANTALUM ALKOXIDES [PDF]

open access: bronzeCanadian Journal of Chemistry, 1962
Ebulliometric studies on the hydrolysis of tantalum pentaalkoxides Ta(OR)5, where R = Me, Prn, Bun, and Bus, have furnished important data on the polymeric nature of tantalum oxide alkoxides. It is shown from the variation of number-average degrees of polymerization as a function of degree of hydrolysis that the polymers conform to certain structural ...
