(1,5-Cyclooctadiene)(methoxy)iridium(I) dimer
CAS 12148-71-9
The methoxy dimer is the high-activity variant for iridium C–H borylation — its basic alkoxide bridge accelerates catalyst activation, making it the specified precursor in many published borylation procedures at low iridium loading.

Where [Ir(COD)(OMe)]₂ is used
High-activity C–H borylation
Paired with dtbpy it activates faster and runs at lower loading than the chloro dimer in arene and heteroarene borylation — the precursor named in most modern borylation protocols.
Ir(I) alkoxide chemistry
A reactive entry to iridium hydride and alkoxide species used in transfer hydrogenation and dehydrogenation research.
Storage and shipping
Storage. Store cold, sealed under inert gas; more air-sensitive than the chloro dimer.
Shipping. Ships in sealed glass under nitrogen by commercial courier.
Packaging. 250 mg · 1 g · 5 g · 25 g

Frequently asked questions
How is pricing structured?
Iridium is among the scarcest PGMs with sharply moving prices, so the metal leg is quoted against the day's Ir price on assayed content and locked at order confirmation; conversion is a stated fabrication charge.
What documentation is included?
Every lot ships with a certificate of analysis stating assayed metal content, plus an English SDS. ICP trace-metal panels are available on request.
Do you take back iridium residues?
Yes — at iridium's price level recovery is almost always worthwhile. Residues, spent coatings and off-spec lots are assayed on receipt and the iridium credited against future supply.
