Description
Tantalum(V) methoxide, also known as tantalum pentoxide methoxide, is an inorganic compound with the chemical formula Ta(OCH3)5. It is a colorless or white crystalline solid that is soluble in organic solvents. Tantalum(V) methoxide is a precursor to various tantalum compounds and has unique properties due to its pentavalent oxidation state and the presence of methoxide ligands.
Uses
Used in Chemical Synthesis:
Tantalum(V) methoxide is used as a precursor in the synthesis of tantalum hydride. It serves as a starting material for the production of tantalum-based compounds, which have potential applications in various fields.
Used in Catalysts:
Tantalum(V) methoxide is used as a component in the preparation of silica-supported alkoxo-tantalum complexes. These complexes are employed as catalysts in the deperoxidation of cyclohexyl hydroperoxide into cyclohexanol and cyclohexanone. This process is important in the production of industrial chemicals and demonstrates the utility of tantalum(V) methoxide in catalysis applications.
Check Digit Verification of cas no
The CAS Registry Mumber 865-35-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 865-35:
(5*8)+(4*6)+(3*5)+(2*3)+(1*5)=90
90 % 10 = 0
So 865-35-0 is a valid CAS Registry Number.

Synthesis and X-ray single crystal study of the bi- and trimetallic alkoxides of molybdenum(VI) and tantalum, Mo2Ta4O8(OMe)16, Mo4Ta4O16(O(i)Pr)12 and LiMo4Ta3O14(O(i)Pr)9(OC2H4OMe)3

The partial hydrolysis of a mixture of molybdenum and tantalum methoxides (Mo:Ta = 1:2) with stoichiometric amounts of water yields a new bimetallic complex Mo2Ta4O8(OMe)16 (I) on crystallization from toluene. The molecules of I appear to be a combination of two MoO2(O(i)Pr)2 units with the earlier described Ta4O4(O(i)Pr)12 core. The thermal reduction of a mixture of MoO(O(i)Pr)4 and Ta2(O(i)Pr)10 (in a 1:1 Mo:Ta ratio) followed by oxidation of the products by dry oxygen, provides access to Mo4Ta4O16(O(i)Pr)12 (II). The same procedure, using LiMo2O4(O(i)Pr)4(OC2H4OMe) instead of MoO(O(i)Pr)4, yielded trimetallic LiMo4Ta3O14(O(i)Pr)9(OC2H4OMe)3 (III) in minor yields. The molecular structure of II can be described as a distorted cube, the corners of which are occupied in turn by [((i)PrO)3Ta(μ-O)3] octahedra and [MoO(μ-O)3] tetrahedra sharing common vertexes. The molecular structure of III can be derived from that of II by replacing one [((i)PrO)3Ta(μ-O)3] octahedron with an [Li(μ, η2-OC2H4OMe)3] trigonal prism (the coordination number of the three Mo atoms is then increased to six).
