说明

一般描述

Acetonitrile (MeCN, ACN) is an aliphatic nitrile that is commonly used as a reaction solvent as well as a chemical intermediate in organic synthesis. In many chromatographic techniques, MeCN is used as a mobile phase solvent due to its low viscosity, high elution strength, and miscibility in water.
 

应用

Acetonitrile can be used as a solvent in:      
  • The solid-phase peptide synthesis.     
  • The sialylation reactions.      
  • The synthesis of copper nanoparticles by reduction of copper nitrate salt using NaBH4. During the preparation, ACN acts as a protecting solvent, which prevents the oxidation of nanoparticles.      
  • The preparation of diaryl selenides by Cu-catalyzed coupling reaction between aryl iodides and diphenyl diselenide. In this process, ACN also functions as a ligand for the copper catalyst to increase its catalytic activity.

特点和优势
