Description

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.
