Tris(triethylphosphite)(tolane)iron, also known as triethylphosphite-toluidine iron complex, is a coordination compound consisting of an iron (Fe) atom coordinated to three triethylphosphite (P(OCH2CH3)3) ligands and one toluene (C7H8) ligand. This organometallic complex is characterized by its unique structure, where the iron atom is surrounded by the three phosphorus atoms from the triethylphosphite ligands and one carbon atom from the toluene ligand, forming a distorted octahedral geometry. The compound is of interest in the field of organometallic chemistry and catalysis, as it can be used as a precursor for the synthesis of various iron-based catalysts and has potential applications in the polymerization of olefins and other industrial processes.

Check Digit Verification of cas no

The CAS Registry Mumber 68643-80-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,6,4 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68643-80:
(7*6)+(6*8)+(5*6)+(4*4)+(3*3)+(2*8)+(1*0)=161
161 % 10 = 1
So 68643-80-1 is a valid CAS Registry Number.

Reaktive ?-Komplexe der elektronenreichen Uebergangsmetalle; VI. Katalysche und stoechiometrische Reaktionen von ?-Aren-Eisenkomplexen mit Alkinen

Funhoff, A.,Schaufele, H.,Zenneck, U.

, p. 331 - 340 (2007/10/02)

The reactive ?-arene complexes bis(ethene)(toluene)iron, (toluene)(1-methylnaphthalene)iron, and bis(tolueneiron)cyclooctatetraene are catalysts for the cyclotrimerization of alkynes RCCR' (R,R' = H, CH3, C2H5, t-C4H9, C6H5, COOCH3) to benzene derivatives.When R = R' = Si(CH3)3, CH2OH or COOH the reaction fails.In the case of bis(ethene)(toluene)iron and acetylenedicarbonic acid dimethylester a cycloaddition of two alkynes and one ethene takes place.When the primary products of the catalytic reaction were trapped with trialkylphosphite, complexes of the type tris(trialkylphosphite)(alkyne)iron and trisbis(trimethylphosphite)diiron, become readily accessible.
