TL;DR: The niobium(V) oxyyalkoxide derivatives [NbO(OCH2CF3)3 · MeCN]2, NbO[OCH 2CF3]2 (OCHCF2) (CF3CH2OH)0.5, [NnO(OEt)3]3] 2, [nbOCl2(Och3)· CH3OH]2 and Nb OCH3)(OC6H4CHO)2 have been obtained by direct alkoxylation
Journal ArticleDOI
The formation of niobium and tantalum oxyalkoxide derivatives from niobium and tantalum alkoxides and alkoxychlorides
L.G. Hubert-Pfalzgraf,J.G. Riess +1 more
TL;DR: In this article, the structure in solution of these oxo derivatives was investigated through low-temperature 1H NMR studies, which was mainly investigated through 1H-NMR studies.
Journal ArticleDOI
Synthesis, characterization and behavior in solution of tantalum(III) and tantalum(IV) halide, hydride and cyclopendienyl dimethylphenylphosphane adducts
TL;DR: In this article, the reduction of tantalum pentahalides by magnesium turnings in CH 2 Cl 2 was investigated in the presence of various phosphanes, and found to be highly dependent on the ligand.
Journal ArticleDOI
Structural and stereodynamic studies on molecular early transition metal derivatives V. NMR study of isolated tungsten dioxofluoride Adducts of type WO2F3L
TL;DR: In this article, a detailed investigation on Et 4 N[WO 2 F 3 (OPMe 3 )] showed that the F atom trans to an oxo ligand, as well as the OPMe 3 ligand trans to the other oxos ligand in the cis-dioxostructure A, are rapidly dissociated on the NMRtimescale, while the apical F atoms trans to each other are not.
Journal ArticleDOI
