The novel sixteen-electron complex (Oq = 8-oxyquinolate; COD = 1,5-cyclooctadiene) adds monodentate phosphines, phosphites or activated olefins irreversibly to give pentacoordinate iridium(I) complexes of the type (L = PPh3, P(OPh)3, maleic anhydride or tetracyanoethylene).Reaction of with some diphosphines leads to substitution products of the general formula (diphos = 1,2-bis(diphenylphosphino)ethane or cis-1,2-bis(diphenylphosphino)ethylene).Carbon monoxide displaces the COD group from the complexes giving either or , and the latter undergo oxidative addition reactions with SnCl4, Me3SiCl, Me3SnCl, MeI, allylbromide, PhCOCl, MeCOCl, Cl2, Br2, TlCl3 and HCl leading to novel iridium (III) complexes.
