description

Tungsten hexacarbonyl is easily vaporized and decomposed by the electron beam — providing a convenient source of tungsten atoms. This product is widely used in electron beam-induced deposition processes, it is also used as a precursor to catalysts for alkene metathesis and to desulfurize organosulfur compounds. It is relatively air-stable, and it is sparingly soluble in non-polar organic solvents. W(CO)6 reactions begin with the displacement of some of its CO ligands. Similar to Mo(CO)6 in behavior, W(CO)6 typically forms compounds that are kinetically more robust. Synthesis of this product are reported (see the links below).

uses

Tungsten hexacarbonyl, [W(CO)6] may be used as a precursor for the deposition of WO3-x films, which may be used as gas sensors for the detection of NO2.Precursor to a Fischer carbene complex which reduces Pd(II) to nanoparticulate Pd(0) that is catalytically active in Hiyama cross-coupling.

Reaction

Volatile starting material used for the atomic layer deposition of tungsten oxide, tungsten nitride. Tungsten hexacarbonyl is used to produce tungsten coatings on base metals. This is done by deposition of the carbonyl on the metal surface, which decomposes to leave a tungsten coating.

Preparation

Tungsten hexacarbonyl is produced by heating tungsten metal with carbon monoxide at high pressure. Also, carbonyl can be prepared by reducing the tungsten hexachloride by heating with iron powder under carbon monoxide pressure.

Chemical Properties

White, volatile, highly refractive, crystalline solid. Decomposes without melting at 150C. One of the more stable carbonyls. Insoluble in water; soluble in organic solvents.

Physical properties

White crystalline solid; density 2.65 g/cm3; decomposes at 170°C without melting; sublimes; vapor pressure 0.1 torr at 20°C; insoluble in water; soluble in most organic solvents.

Uses

Different sources of media describe the Uses of 14040-11-0 differently. You can refer to the following data:
1. Tungsten Hexacarbonyl is an useful catalyst in carbonyation amines, as well as an stable source of tungsten atoms through electron beam-induced depostion.
2. Tungsten coatings on base metals by deposition and decomposition of the carbonyl.

General Description

Atomic number of base material: 74 Tungsten

Health Hazard

Toxicity of this compound is not reported.Although air stable at ambient temperature,upon heating it emits toxic carbonmonoxide. Chronic exposure to its vaporsor dusts can cause bronchitis. Ingestion islikely to produce the toxic effect of tungstenoxides.

Fire Hazard

It explodes when heated to high temperature. Solution in ether can explode if stored for a long time.

Purification Methods

Sublime it in vacuo before use [Connoe et al. J Chem Soc, Dalton Trans 511 1986]. TOXIC.

Check Digit Verification of cas no

The CAS Registry Mumber 14040-11-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,4 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14040-11:
(7*1)+(6*4)+(5*0)+(4*4)+(3*0)+(2*1)+(1*1)=50
50 % 10 = 0
So 14040-11-0 is a valid CAS Registry Number.

Investigation of the catalytic properties of the thermally activated dichloro-tetracarbonyl-tungsten in olefin metathesis reaction

Bencze, Lajos,Szalai, Gabor,Overton, Tina L.

, p. 5 - 7 (1997)

Combined catalytic, preparative and spectroscopic studies revealed that the ring-opening metathesis polymerisation of norbornene initiated by thermally activated W (CO)4Cl2 (I) proceeds mainly on the surface of a solid decomposition product formed in situ.

Reactivity of cyano- And isothiocyanatoborylenes: metal coordination, one-electron oxidation and boron-centred Br?nsted basicity

, p. 7937 - 7942 (2021)

Doubly base-stabilised cyano- and isothiocyanatoborylenes of the form LL′BY (L = CAAC = cyclic alkyl(amino)carbene; L′ = NHC = N-heterocyclic carbene; Y = CN, NCS) coordinate to group 6 carbonyl complexesviathe terminal donor of the pseudohalide substituent and undergo facile and fully reversible one-electron oxidation to the corresponding boryl radical cations [LL′BY]˙+. Furthermore, calculations show that the borylenes have very similar proton affinities, both to each other and to NHC superbases. However, while the protonation of LL′B(CN) with PhSH yielding [LL′BH(CN)+][PhS?] is fully reversible, that of LL′B(NCS) is rendered irreversible by a subsequent B-to-CCAAChydrogen shift and nucleophilic attack of PhS?at boron.

Photochemische Reaktion von Pentacarbonyl(1-ethoxy-2-methyl-2-propenyliden)wolfram und Dekacarbonyldirhenium

Upon UV irradiation at 223 K pentacarbonyl (1-ethoxy-2-methyl-2-propenylidene)tungsten (1) and decacarbonyl-dirhenium (2) yield enneacarbonyl(μ-η1:3-1-ethoxy-2-methyl-2-propenylidene)ditungsten (3), octacarbonyl(μ-η1:3-1-ethoxy-2-methyl-2-propenylidene)dirhenium (4) and tridecacarbonyl-μ-η1:3-1-ethoxy-2-methyl-2-propenylidene)dirhenium-tungsten (5).The molecular structure of the hetero-trinuclear compound 5 was determined by X-ray structure analysis.The three metal centers form a bent Re-W-Re spine.One of the Re-W bonds is bridged by a carbonyl and the η1:3-1-ethoxy-2-methyl-2-propenylidene ligand.

Siliciumhaltige Carben-Komplexe. XIV. Untersuchungen zur Frage der Aciditaet der Si-H-Gruppe in Silylcarben-Komplexen (CO)5MC(XR)SiHR'2 (M = Cr, W; XR = OEt, NR2)

Schubert, Ulrich,Wuelfert, Peter,Mock, Stefan

, p. 55 - 64 (1993)

The very unstable carbene complexes (CO)5MC(OEt)Si(H)Mes2 (1a: M=W; 1b: M=Cr; Mes=mesityl) were prepared by reaction of M(CO)6 with Li, followed by alkylation with BF4.Corresponding complexes with smaller substituents at the silicon atom were considerably less stable.While 1a yielded the aminocarbene complexes (CO)5WC(NHR)Si(H)Mes2 upon reaction with H2NR (R=Me, Et, CH2CH=CH2, i-Pr), reaction with HNR2 was strongly influenced by steric effects.Dialkylaminocarbene complexes (CO)5WC(NR2)Si(H)Mes2 were only obtained with the sterically less demanding amines HNMe2 or HNC4H8.Complex 1b only reacted with H2NMe.The X-ray structure analysis of (CO)5WC(NC4H8)Si(H)Mes2 (2f) showed that the hydrogen atom at silicon is strongly screened and hardly accessible.Although spectroscopic data of the new complexes indicate a slight enhancement of the acidity of the Si-H group compared with R2SiH2, no deprotonation was possible using several bases.
