설명

애플리케이션

Ethylenediamine (1,2-Diaminoethane, DAE) can be used as a reagent to prepare various metal ion complexes, which are employed as reducing agents in the following reduction reactions.

• DAE/Cr(II) complex is used 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/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.
