Diphosphenyl complexes (h5-C5Me5)(CO)2MP:PR [M = Fe, Ru, Os; R = 2,4,6-(Me3C)3C6H2, C5Me5 = pentamethylcyclopentadienyl] react with Fe2(CO)9 to yield adducts such as (h5-C5Me5)(CO)2M[Fe(CO)4]P:PR (I) as well as the 1,3-diphosphapropanone complexes II by catalytic carbonylation of the activated P:P double bond. The structures of I (M = Fe) and II (M = Fe) are established by x-ray diffraction studies.
