Product Information

• Name: Tris(2-phenylpyridine)iridium
• Brand: Biosynth
• Description: Tris(2-phenylpyridine)iridium (IrCl) is a coordination compound that is used as a catalyst to initiate cationic polymerization of biphenyl. It is also used as an analytical reagent for determining the content of fatty acids in oils and fats. The steric interactions between the phenyl groups and the electron-rich iridium atoms lead to a high degree of conversion of ethylene oxide to ethylene glycol, which can be observed by UV absorption. The synthesis of IrCl occurs in two steps: first, the reaction of chloroacetone with phenylmagnesium bromide followed by addition of hydrated iridium chloride. The product crystallizes in red needles, which are analyzed using x-ray crystal structures. Analysis using nmr spectroscopy reveals that IrCl contains four nitrogen atoms and three oxygen atoms. Its redox potentials are -0.9 volts for oxidation and +1.3 volts for reduction, making
