 Title    Reaktionen koordinierter Liganden, VI [1] Substituenteneinflüsse bei der Bildung von Tri-und Tetraphosphinen in der Koordinationssphäre von Übergangsmetallen Reactions of Coordinated Ligands, VI [1] Influence of Substituents on the Formation of Tri-and Tetraphosphines in the Coordination Sphere of Transition Metals  
 Abstract    The lithiumphosphido complex cis-Mo(CO)4(Me2PLi)2 reacts with dichlorophosphines RPCI2 (R = Ph, Bu') to give coordination compounds of tetraphosphines Me2P-PR-PR-PMe2, whereas the complex of the triphosphine eis -Mo (CO)4 (Ph2P-PMe-PPh2) is obtained starting with the lithiumphosphido complex cis-Mo(CO)4(Ph2PLi)2. Phenyldilithiumphosphine and the chlorophosphine complexes cis-Mo(CO)4(R2PCl)2 (R = Me, Ph) give in low yield cis-Mo(CO)4(R2P-PPh-PPh-PR2) and cis-Mo(CO)4(R2P-PPh-PR2). The mechanisms of these reactions are discussed. The {3ippjj-and { 1 H} 31 P-NMR spectra are analysed and correlated with the structures of these complexes.
