A sample of ethylenediamine, a simple ethyleneamine. Ethyleneamines are a class of amine compounds containing ethylene (-CH 2 CH 2-) linkages between amine groups.These compounds are generally colorless, low-viscosity liquids with a fishy amine odor.
The bond angles in aziridine are approximately 60°, considerably less than the normal hydrocarbon bond angle of 109.5°, which results in angle strain as in the comparable cyclopropane and ethylene oxide molecules.
Polyethylenimine (PEI) or polyaziridine is a polymer with repeating units composed of the amine group and two carbon aliphatic CH 2 CH 2 spacers. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups.
Mitomycin C, an aziridine, is used as a chemotherapeutic agent by virtue of its antitumour activity. [1]In organic chemistry, aziridines are organic compounds containing the aziridine functional group (chemical structure (R−) 4 C 2 N−R), a three-membered heterocycle with one amine (>NR) and two methylene bridges (>CR 2).
Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C 2 H 4 (NH 2) 2.This colorless liquid with an ammonia-like odor is a basic amine.It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. [6]
Binary ethylenimine (BEI) is a preparation of aziridine.It can be produced by heating bromoethylamine hydrobromide or 2-aminoethyl hydrogen sulfate in the presence of sodium hydroxide (Gabriel method).
The Wenker synthesis is an organic reaction converting a beta amino alcohol to an aziridine with the help of sulfuric acid.It is used industrially for the synthesis of aziridine itself.
