  Tetraphenyldiphosphine monoxide forms complexes of the type(CO)5M[PPh2P(O)Ph2] with Group VIB metals (M = Cr, Mo, W). The crystal and molecular structure of the Mo-complex has been determined:MoP2O6C29H20, Monoclinic Space Group P21/n,a 13.776(1),b 16.811(2),c12.162(1)Å, β 90.36(1)°;Z = 4 and Dc 1.47 Mg m−3. RF is 0.038 for 5006observed reflections. The Mo atom is found to be coordinated to the originally

  Various [Cr(CO)(4)(P boolean AND P)](+) complexes have been synthesized and tested for the tetramerization of ethylene to give principally 1-octene. The effect of the anion has been investigated, and it has been found that for successful catalysis an extremely weakly coordinating anion is required. This study shows that when [Al(OC(CF3)(3))(4)](-) is employed as the anion, along with triethylaluminum and PNPiPr as the coordinated diphosphine, the system is active for the tetramerization of ethylene. This is the first example of Cr-I being used as a catalyst precursor for selective tetramerization and gives evidence toward the catalytic cycle acting through a Cr-I -> Cr-III cationic mechanism.
