12129-70-3 Usage

General Description

Tetracarbonyl(1,5-cyclooctadiene)tungsten is a chemical compound with the formula W(CO)4(C8H12). It is used as a catalyst in organic synthesis, particularly in the production of fine chemicals and pharmaceuticals. TETRACARBONYL(1 5-CYCLOOCTADIENE)TUNGST& is a stable organotungsten complex and is typically used in a variety of reactions including hydrogenation, isomerization, and carbonylation. Tetracarbonyl(1,5-cyclooctadiene)tungsten is a valuable tool in the field of organic chemistry due to its ability to facilitate a wide range of chemical transformations.

Check Digit Verification of cas no

The CAS Registry Mumber 12129-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,2 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12129-70:
(7*1)+(6*2)+(5*1)+(4*2)+(3*9)+(2*7)+(1*0)=73
73 % 10 = 3
So 12129-70-3 is a valid CAS Registry Number.

Isomeric olefin tetracarbonyl complexes of tungsten(I): An infrared spectroelectrochemical study at low temperatures

Gorski, Marcin,Hartl, Frantisek,Szymanska-Buzar, Teresa

, p. 4066 - 4071 (2008/10/09)

In situ electrolysis within an optically transparent thin-layer electrochemical (OTTLE) cell was applied at 293-243 K in combination with FTIR spectroscopy to monitor spectral changes in the carbonyl stretching region accompanying oxidation of four tetrac

DINUCLEAR μ-ALKYLIDENE COMPLEXES OF TUNGSTEN FROM MONONUCLEAR, HETEROATOM-SUBSTITUTED VINYL-ALKYLIDENE COMPLEXES OF THIS METAL

Parlier, A.,Rose, F.,Rudler, M.,Rudler, H.

, p. C13 - C15 (2007/10/02)

A general synthesis of homodinuclear μ-alkylidene complexes of tungsten, starting from Fischer type alkylidene complexes of tungsten is outlined.Thus the vinyl-alkylidene complexes (CO)5W=C(OMe)CHCHR react with (CO)5W=CPh2, as a source of coordinatively unsaturated w(CO)4, to give the dinuclear complexes W2(CO)9(OMe)CHCHR, and the complex (CO)5W=C(OMe)CHCH2 reacts slowly in hydrocarbon solution, in the absence of (CO)5W=CPh2, to give a dinuclear complex W2(CO)19C(OMe)CHCH2 in which the two metal centers are not bound together: this product is the result of coordination of the double bond of the starting material to a W(CO)5 species.
