Usage

Uses

Tantalum(V) methoxide is used in the synthesis of tantalum hydride. Silica-supported alkoxo-tantalum complexes were used in the deperoxidation of cyclohexyl hydroperoxide into cyclohexanol and cyclohexanone.

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).
