 Abstract    von Silylphosphanen mit Halogenokomplexen von Übergangsmetallen: Synthese, Struktur und Eigenschaften von Komplexen des Typs cis-X(CO)4Mn{PPh3 _"(SiMe3)/I} (n = 1 -3) und [{Cp(CO)2Fe}2PPhR]X (R = Ph, H) bzw. [{Cp(CO)2Fe}3PH]X (X = CI, Br, I) Reactions of Silylphosphanes with Halogeno Complexes of Transition Metals: Synthesis, Structure and Properties of Complexes c«-X (C O)4 M n{PPh3 _"(SiMe3)"} (n = 1 -3) , [{Cp(CO)2Fe}2 PPhR]X (R = Ph, H) and [{Cp(CO)2Fe}3 PH]X (X = Cl, Br, I) The reactions o f pentacarbonylm anganese halides (C O)5M nX (X = Cl, Br, I) with the silyl­ phosphanes Ph3_"P(SiMe3)" (n = 1—3) at am bient temperature result in the elimination o f one CO ligand and the formation o f cw-configurated substitution products X (C O)4M n{PPh3_"(SiMe3)"}. N o CO -substitution, but M e3SiX-elim ination is observed in the reaction of Ph3_"P(SiMe3)" with the dicarbonylcyclopentadienyliron halides C pFe(C O)2X to give the di-and triferriophosphonium halides [{C p (C O)2F e}2P PhR ]X (R = Ph, H) and [{C p(C O)2F e }3PH]X (X = Cl, Br, I). The mass, IR and NM R spectra are reported and discussed. The crystal structures o f cz's-I(CO)4M nPPh2SiM e3 and [{C p (C O)2F e}2PPh2]I have been determined.
