Cyclooctadiene iridium methoxide dimer is an organoiridium compound with the formula Ir2(OCH3)2(C8H12)2, where C8H12 is the diene 1,5-cyclooctadiene. It is a yellow solid that is soluble in organic solvents. The complex is used as a precursor to other iridium complexes, some of which are used in homogeneous catalysis.[1]
The compound is prepared by treating cyclooctadiene iridium chloride dimer with sodium methoxide.[2] In terms of its molecular structure, the iridium centers are square planar as is typical for a d8 complex. The Ir2O2 core is folded.[3]
An example of where this catalyst was used is in the synthesis of doravirine.
