Application

Copper(I) iodide can be used as a catalyst for:
  • For arylation of pyrazole and derivatives by coupling arenediazonium species under mild and ligand-free conditions.
  • Selective cross-coupling of dibromo alkenes and heteronucleophiles which leads to numerous building blocks such as 1-bromoenamides, ynamides, ketene N, N-acetals, 1-bromoenol ethers, ynol ethers, ketene O, O-acetals, and vinyl phosphonates.
  • Stereospecific and the regioselective reaction of silacyclopropanes with carbonyl compounds.
It can also be used as a starting material in the preparation of diphenylphosphinepyridine-derivatives (PyrPHOS)-copper iodide complexes which are suitable for use in OLEDs.

Features and Benefits

  • Low toxicity
  • Mild reaction condition
  • High purity ensures reproducibility and avoids cocatalysis by contaminants.

White light-emitting diodes (WLEDs) are promising next-generation solid-state light sources. However, the commercialization route for WLED production suffers from challenges in terms of insufficient color-rendering index (CRI), color instability, and incorporation of rare-earth elements. Herein, a new two-component strategy is

Free NH 3,3-diarylacrylamides are cyclized to substituted 2-quinolones in the presence of CuI, PPh(3), and KO-t-Bu in o-xylene at 100 °C. The reaction proceeds through a C-H functionalization/C-N bond formation process. With unsymmetrical 3,3-diarylacrylamides, high selectivity is observed using substrates

The first asymmetric total synthesis and determination of the absolute configuration for the neuroactive marine macrolide palmyrolide A is described. The highlight of the synthesis is macrocyclization via trans-enamide formation catalyzed by copper(I) iodide and cesium carbonate. Comparison with the
