Description

TCI C2985 Chlorobis(cyclooctene)iridium(I) Dimer, CAS number 12246-51-4, is an organometallic iridium complex that serves as a catalyst precursor. Its dimeric structure links two iridium centres through chloride bridges, with weakly bound cyclooctene ligands coordinated to each metal. In catalysis laboratories, this compound is widely used to generate the active catalytic species directly in the reaction flask, particularly in carbon–hydrogen bond activation transformations. The combination of an electron-rich iridium metal centre and readily displaced ligands makes this compound a practical entry point into a wide range of modern catalyst systems.

The most defining property of this complex is the lability of its cyclooctene ligands. These alkene ligands are easily released when a supporting ligand such as a phosphine, an N-heterocyclic carbene, or a bipyridine is added, allowing researchers to assemble catalysts with the desired electronic and steric characteristics without requiring complicated preparation procedures. The iridium(I) centre, with its electron-rich configuration, is well suited to the oxidative addition step at C–H bonds that are normally difficult to activate. Because of this high reactivity, the compound must be handled with appropriate care during weighing and transfer.

In Indonesian laboratories, this iridium dimer is typically used in university research groups and institutional chemistry laboratories working on catalysis and organometallic synthesis. It is generally applied at small scale in methodology studies, where the precursor is combined in situ with a chosen supporting ligand before the substrate is introduced. Researchers commonly work with it under inert atmosphere conditions using standard Schlenk or glovebox techniques, consistent with the general practice for air-sensitive organometallic reagents.

Laboratory Applications

  • C–H bond activation studies: the electron-rich iridium(I) centre readily undergoes oxidative addition into carbon–hydrogen bonds that conventional reagents cannot activate under mild conditions.
  • In situ catalyst generation: the labile cyclooctene ligands allow the active catalytic species to be formed directly in the reaction flask without isolating an intermediate complex.
  • Ligand screening in methodology research: phosphines, N-heterocyclic carbenes, and bipyridines can each be introduced to build catalysts with different electronic and steric profiles from one precursor.
  • Organometallic synthesis: the chloride-bridged dimeric framework provides a convenient starting point for preparing a variety of defined iridium(I) coordination complexes.
  • Academic catalysis teaching and research: the compound offers a practical, well-established entry route into modern iridium catalyst systems for university and institutional research groups.

Handling and Storage

Store this iridium complex under an inert atmosphere in a tightly closed original container, kept in a cool, dry, well-ventilated area away from heat sources, moisture, and oxidising agents. Because the compound is a reactive, air-sensitive organometallic precursor, weighing and transfer are best carried out inside a glovebox or using standard Schlenk line technique to limit exposure to air. Handle in a fume hood while wearing a laboratory coat, chemical-resistant gloves, and safety goggles. Return the container promptly to its designated storage location after use, keep it clearly labelled, and dispose of residues and contaminated materials in accordance with the applicable chemical waste procedures of your laboratory. Always consult the manufacturer's safety data sheet before use.
