Anwendungen

1,5-Cyclooctadiene(pyridine)(tricyclohexylphosphine)iridium(I) hexafluorophosphate is used as a catalyst for hydrogenation of mono-, di-, tri-, and tetra-substituted substrates and the isomerization and hydroboration of alkenes. It is also used in isotope exchange reactions, especially the direct exchange of a hydrogen atom with its isotopes deuterium and tritium. Carbonyl groups are also known to direct the hydrogenation by the Crabtree catalyst is highly regioselective.

Bemerkungen

Moisture sensitive. Incompatible with oxidizing agents.
