Vanadium-Lithium Alkoxides: Synthesis, Structure, Spectroscopic Characterisation and Accidental Degradation of Silicone Grease
Dois complexos contendo vanádio e lítio, [V 6 Li 10 O 8 (ONep) 14 {OSi(Me) 2 (ONep)} 2 ] (1) e [V(ONep) 3 (μ-ONep) 2 Li(thf) 2 ] (2), Nep = neopentila, Me = metila e thf = tetraidrofurano, foram isolados em alto rendimento e caracterizados por diversas técnicas incluindo espectroscopias de ressonância paramagnética eletrônica (RPE, banda X) e ressonância magnética nuclear (RMN) de Si, medidas d...
متن کاملSynthesis, characterisation and catalytic properties of vanadium substituted mesoporous aluminophosphates
Vanadium substituted mesoporous AlPO have been synthesised using structure-directing surfactant under hydrothermal synthesis conditions. The presence of V in the framework of AlPO has been established by ESR, XPS, UV–vis DRS and ICP-AES measurements. This system is capable of promoting the oxidation of toluene to aldehyde and benzoic acid when the oxidising agent is 70% tert-butyl hydroperoxide...

متن کاملSynthesis and characterisation of new titanium amino-alkoxides: precursors for the formation of TiO2 materials.
Reaction of the amino-alkoxides HOCH(CH(2)NMe(2))(2) (Hbdmap) and HOC(CH(2)NMe(2))(3) (Htdmap) with [Ti(OR)(4)] yields a series of heteroleptic titanium alkoxides [Ti(OR)(4-n)(L)(n)] (L = bdmap, tdmap). Substitution of the monodentate alkoxide with the chelating alkoxides becomes progressively more difficult, with homogeneous products being obtained only for n = 1, 2. The structure of [Ti(OEt)(...
متن کاملSynthesis, Spectroscopic and X-Ray Structure Characterisation of Bis(tetramethylammonium) and Bis(tetra-n-butylammonium) Tetrathiomolybdates
The new tetraalkylammonium tetrathiomolybdates (Me4N)2[MoS4] (1) and (nBu4N)2[MoS4] (2) were prepared via a direct salt substitution using (NH4)2[MoS4] as starting material. Compound 1 crystallises in the non-centrosymmetric orthorhombic space group P212121 with a = 8.9233(4), b = 15.5210(9) and c = 37.255(3) Å. Compound 2 crystallises in the orthorhombic space group Fdd2 with a = 28.9142(18), ...
