Organometallphosphin-substituierte Übergangsmetallkomplexe, XXVII [1] Reaktionen von Pentacarbonylmangan-und Pentacarbonylrheniumbromid mit Organoelement(rVb)phosphinen / Organometalphosphine-Substituted Transition Metal Complexes, XXVII [1] Reactions of Pentacarbonylmanganese-and Pentacarbonylrheniumbromide with Organoelement(IVb) Phosphines

Abstract

Abstract The reactions of pentacarbonyl manganese bromide and pentacarbonyl rhenium bromide with di(tert-butyl)trimethylsilyl phosphine, teri-butyl-bis(trimethylsilyl)-, -(germyl)-, -(stannyl) phosphine, as well as with tris(trimethylsilyl)-, -(germyl)-, and -(stannyl) phosphine result in the elimination of one CO ligand and the formation either of corresponding bromo-tetracarbonyl(organometalphosphine)manganese or -rhenium complexes or of corresponding octacarbonyl-bis(μ-organometalphosphido)dimanganese or -dirhenium complexes. The IR, NMR, and Mössbauer spectra are reported and discussed.
