Title: Tricyclohexylphosphine complexes of rhodium(I), rhodium(II), iridium(I) and iridium(III)
Abstract: The preparation of iridium and rhodium complexes with tricyclohexylphosphine (PCy3) is reported. Paramagnetic rhodium(II) complexes of the type RhX2(PCy3)2 with XCl or Br were prepared. The reaction between iridium salts with PCy3 in propanol-2 resulted in diamagnetic complexes with iridium halogenide ratio 1:2. The possible structures of these compounds are discussed. Complexes of the type MCl(CO)(PCy3)2 with MRh or Ir and IrHCl2(CO)(PCy3)2 are described and characterized.
