General Description

1,2-Diisocycanoethane is a chemical compound with the molecular formula C6H8N2. It is a colorless liquid that is primarily used as a chemical intermediate in the production of other organic compounds. 1,2-Diisocycanoethane is a diisocyanate, which means it contains two isocyanate functional groups. Due to its reactivity, it is commonly used in the production of polyurethanes, coatings, adhesives, and elastomers. It is also used as a crosslinking agent in the production of plastics and synthetic fibers. However, 1,2-Diisocycanoethane is a hazardous chemical and should be handled with caution, as it can cause skin and respiratory irritation and may be toxic if ingested or inhaled. Therefore, proper safety precautions must be taken when working with this compound.

CONFORMATION AND VIBRATIONAL SPECTRA OF 1,2-DIISOCYANOETHANE

The infrared spectra of 1,2-diisocyanoethane as a vapour, liquide crystalline solid, and in several solvents have been measured.Raman spectra were recorded for the liquid including semiquantitative polarization measurements.The data were interpreted in terms of an equilibrium between trans and gauche rotamers.The crystalline solid contains the pure gauche rotamer.In the liquid at ambient temperatures the energy difference between the conformers is very small.This also holds for aqueous solutions, while apolar solvents favour the trans rotamer.In the vapour at 100 deg C, the most stable form is the trans conformer.A complete vibrational assigment has been proposed for both conformers.Semiempirical calculations at the INDO level indicate about equal stabilities of the two conformers, slightly favouring the gauche form.

Reaction of Bidentate Isonitrile Ligands with Iron Carbonyls

Reaction of the bidentate isonitriles CN(CH2)nNC ( n =2, 3, 4, or 6) with (cp = η-cyclopentadienyl) yields exclusively 2> derivatives which are fluxional in solution and exist in three isomeric forms (bridged-bridged, bridged-terminal, and terminal-terminal with respect to the bonding mode of the bidentate isonitrile).The proportion of the isomers containing terminally bound isonitrile increases with the length of the alkyl chain.The complexes may be protonated to yield 2>2 salts (n = 2 or 6) and may be cleaved with I2 to give and 2nNC>> (n = 2 or 6).Reaction ofCN(CH2)nNC (n = 2 or 6 with or yields exclusively 2nNC>>
