Reactions of Biscyclopentadienyl Vanadium with NO and XNO

چکیده
Very few nitrosyl derivatives of the first transition elements are known [1, 2], [^-C5HsCr(NO)2]2 has been obtained by reduction of ^-CsHsCrNOCl with sodium borohydride [3]. The only known cyclopentadienylnitrosyl vanadium complexes are T?-C5H5V(NO)2CO [4] and the cation [>?-C5H5V(NO)3]+ [5]. The most important methods used to obtain these complexes consist of treatment of carbonyl complexes with nitrosyl chloride or nitric oxide [6, 7], although more recently [8] they have been obtained by oxidative addition reactions with NO2BF4. We have obtained nitrosyl derivatives of bis(cyclopentadienyl) vanadium by oxidative addition of NO and XNO (X = Cl or Br).

Reactions of Dicyanogen and Cyanogen Halides with the Biscyclopentadienyls of Vanadium and Chromium
The oxidative addition of dicyanogen, (CN)2, and of the cyanogen halides, XCN (X = Cl, Br or I), to the biscyclopentadienyl compounds of vanadium and chromium, (/y-C^Hs^M (M = V or Cr), leads to the formation of (/?-C5H5)2MX(CN) (X = CN, Cl, Br, I ; M = V or Cr). The synthesized compounds have been characterized by elemental analyses, IR and EPR spectra, and determinations of the magnetic moments.
متن کاملسینتیک تشویه پنتا اکسید وانادیم با کربنات سدیم
Vanadium is distributed widely and scarcely (150 ppm) on the earth. Its major applications are in steelmaking, dye-production and catalyst-fabrication industries. With the ever-increasing demand for this metal, secondary resource-exploitation of such waste materials as spent catalysts is recommended. Many reactions are involved in vanadium-extraction from these resources. Since roasting in comp...

The Fe3O4@SiO2@APTMS@Glu-His@V complex was prepared with modification of iron oxide magnetic nanoparticles with (3-aminopropyl) trimethoxysilane (APTMS) and glutaraldehyde-L-histidine Schiff base followed by complexation with VOSO4. Characterization of the Fe3O4@SiO2@APTMS@Glu-His@V complex was carried out by means of FTIR, XRD, SEM, EDX, TEM, AAS and VSM techniques. It was found that Fe3O4@SiO...
متن کاملOne-pot Synthesis of Polysubstituted Dihydro-2oxypyrroles Catalyzed by Vanadium (V) oxide
A mild and efficient synthesis of polysubstituted dihydro-2-oxypyrroles has been developed for the one-pot, four-component domino condensation of dialkyl acetylenedicarboxylate, formaldehyde and aromatic amines using Vanadium (V) oxide as the catalyst at ambient temperature. The use of Vanadium (V) oxide makes this process simple, more convenient, and environmentally friendly.
