Description

Description générale

Ethylenediamine (en) is a linear aliphatic diamine that can be synthesized by reacting ethanolamine and ammonia in the presence of zeolite catalyst. Its effect as an allergen has been investigated. It participates in the synthesis of metal chalcogenides and thiogallates.

Application

Ethylenediamine (1,2-Diaminoethane, DAE) can be used as a reagent to prepare various metal ion complexes. For instance, DAE reacts with chromium(II) salts forms a Cr(II)/DAE complex, which is used as an efficient reducing agent for the reduction of primary alkyl halides to alkanes, and aryl bromides or iodides to arenes. This complex is also used to reduce β-substituted alkyl halides and epoxides to alkenes.
DAE can also be used in the following reduction reactions:

• DAE/Borane (1:1) complex is used as a highly selective reducing agent for the conversion of cinnamaldehyde to cinnamyl alcohol.
• DAE/Li complex is used as an efficient reagent for the reduction of alkenes, aromatic hydrocarbons, phenols, and alcohols.

Ethylenediamine (en) has been used in the following process:

• Synthesis of nucleus pulposus (NP)-like collagen-glycosaminoglycans (CG) core.
• Surface modification of epoxy-activated cryogel.
• Alteration of the surface of carbon nanoparticles (CNPs) to generate CNPs-ethylene.

It may be used in the following studies:

• Surface modification of triazolate-bridged metal-organic framework.
• As a solvent in the synthesis of ZnS (zinc sulfide) and ZnSe (zinc selenium) precursors by solvothermal process.
• As a reactant in the synthesis of Pd/C-ethylenediamine complex catalyst.
• As a chelating agent in the synthesis of β-Co(OH)₂ nanocrystals.
• Synthesis of ethylenediamine-templated iron arsenates and fluoroarsenates.
• As a template agent and coordination agent in the synthesis of CdS (cadmium sulfide) nanocrystals.
