Ir Complexes with P4 Bicyclotetraphosphane and P8 Cunean as Ligands - CO Insertion into an Ir-P Bond

Article abstract of DOI:10.1002/cber.19961290619

The reaction of [Cp*Ir(CO)₂] with white phosphorus under photochemical or thermal conditions produces the bicyclotetraphosphane complexes 1 and 2 and the cunean-type complex 3. The products were characterized by NMR, IR, and mass spectroscopy as well as by X-ray structure analyses. Complex 1 reacts with CO with insertion into a Ir-P bond to form 2 and finally [CpIr(CO)₂].
