37220-42-1 Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 37220-42-1 differently. You can refer to the following data:
1. Mobile, yellow liquid.Evolves carbon monoxide on exposure to air or light. Soluble in nickel tetracarbonyl and most organic solvents; soluble with decomposition in acids and alkalies; insoluble in water.
2. Iron pentacarbonyl reacts with cyclopentadiene at 135° in an autoclave to give the binuclear complex [(π-C5H5)Fe(CO)2]2 as deep reddish-purple crystals which are stable to air and water. The crystal structure determination shows this molecule to be centrosymmetric with two bridging carbonyls forming a plane with the two iron atoms [Fig. 19(a)]. The rather short Fe-Fe distance of 2-49 ? and the diamagnetism of the compound indicate the presence of the Fe-Fe bond. In solution, however, it tautomerizes to the structure believed to be that shown in Fig.19(b),in which the two rings lie on one side of the mean plane formed by the bridging carbonyl groups and the iron atoms and the two terminal CO groups lie on the other side.

Uses

Different sources of media describe the Uses of 37220-42-1 differently. You can refer to the following data:
1. Catalyst in organic reactions, carbonyl iron for high-frequency coils.
2. Iron pentacarbonyl is a useful dehalogenating and carbonylating agent.

Hazard

Flammable, dangerous fire risk. Toxic by ingestion, inhalation, and skin absorption.

Structure and conformation

The trigonal bipyramidal structure has been preferred to the square pyramidal one in the interpretation of electron diffraction, Raman and infrared and thermodynamic data; the apparently contradictory dipole moment of 0-8 D being attributed to atom polarization. A single crystal X-ray structure determination at - 80°C has confirmed the trigonal bipyramidalstructure.

Check Digit Verification of cas no

The CAS Registry Mumber 37220-42-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,2,2 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 37220-42:
(7*3)+(6*7)+(5*2)+(4*2)+(3*0)+(2*4)+(1*2)=91
91 % 10 = 1
So 37220-42-1 is a valid CAS Registry Number.

Phase Transfer Generation of Acyltetracarbonyliron Anions: their Role in the Phase Transfer Carbonylation of Reactive Halides to give Carboxylic Acids and Symmetrical and Unsymmetrical Ketones

Laurent, Pascale,Tanguy, Guy,Abbayes, Herve des

, p. 1754 - 1756 (1986)

Acyltetracarbonyliron anions RCOFe(CO)4(1-) (3) are readily synthesised under mild phase transfer (PT) conditions from pentacarbonyliron and reactive organic halides; the in situ generated anions (3) (R = ArCH2) are the true catalysts in the PT carbonylation of benzyl halides to give ketones or carboxylic acids.

Phosphorus-carbon bond forming reactions of iron tetracarbonyl-coordinated phosphenium ions

King, Ryan C.,Nilewar, Shrikant,Sterenberg, Brian T.

, p. 68 - 74 (2018/11/21)

Abstraction of chloride from [Fe(CO)4(PPh2Cl)] (1) in the presence of PPh3 leads to [Fe(CO)4(PPh2(PPh3))][AlCl4] (2), an iron complex of a phosphine-coordinated phosphenium ion. The PPh3 is readily displaced by ferrocene, leading to an electrophilic aromatic substitution reaction, and formation of [Fe(CO)4{PPh2Fc}] (3) (Fc = ferrocenyl). Alternately, chloride abstraction from 1 in the presence of ferrocene leads directly to 3, via a transient phosphenium ion complex. The transient phosphenium ion complex also reacts with N,N-diethylaniline, indole, and pyrrole to form the respective p-anilinyl, 3-indolyl, and 2-pyrryl phosphine complexes via electrophilic aromatic substitution. Chloride abstraction from [Fe(CO)4(PPhCl2)] in the presence of ferrocene leads to a double substitution reaction, forming [Fe(CO)4{PPhFc2}] (13).

Coordination chemistry and oxidative addition of trifluorovinylferrocene derivatives

Heinrich, Darina,Schmolke, Willi,Lentz, Dieter

, p. 105 - 112 (2016/11/11)

Complexes using trifluorovinylferrocene and 1,1′-bis(trifluorovinyl)ferrocene as ligands can be obtained by the reaction with a series of fragments of transition metal complexes. Formation of [Pt(η2-trifluorovinylferrocene)(PPh3)2] (1), [{Pt(PPh3)2}2(η2-1,1′-bis(trifluorovinyl)ferrocene)] (2) and [Pt(η2-1,1′-bis(trifluorovinyl)ferrocene)(PPh3)2] (3) were achieved by ligand substitution in [Pt(η2-CH2?=?CH2)(PPh3)2]. Treatment of eneacarbonyldiiron with trifluorovinylferrocene provided [Fe(CO)4(η2-trifluorovinylferrocene)] (4). Photolytically activated reactions of [MnCp(CO)3] and [MnCp′(CO)3] (Cp′?=?C5H4CH3) afforded [MnCp(CO)2(η2-trifluorovinylferrocene)] (5a) and [MnCp′(CO)2(η2-trifluorovinylferrocene)] (5b) respectively. [Ni(η2-trifluorovinylferrocene)(Cy2P(CH2)2PCy2)] (6) could be obtained by reaction with [Ni(COD)2] and Cy2P(CH2)2PCy2. Furthermore the C[sbnd]F bond activation by oxidative addition in the presence of lithium iodide yielding two isomers of [PtI{η1-difluorovinylferrocene}(PPh3)2] (7a/7b) is presented. Molecular structures of 1, 4 and 7a were elucidated using X-ray single crystal diffraction. The spectroscopic and structural data of these complexes prove the powerful π acceptor abilities of these ligands.
