Metallkomplexe mit biologisch wichtigen Liganden XXVI : Reaktionen von Bis(α-aminoacidato)platin(II)-Komplexen mit Nitrosylsalzen: Nitrosylplatin-Komplexe[xxx] + X- (X = BF4 , PF6 , SbF6 )/Metal Complexes with Biologically Important Ligands XXXVI : Reaction of Bis(α-aminoacidato) Platinum(II) Complexes with Nitrosyl Salts: Nitrosyl Platinum Complexes[xxx]+X-(X = BF4 , PF6 , SbF 6)

Abstract

Abstract The reactions of the glycinato, alaninato, or cyclo-leucinato chelate platinum complexes trans -[xxx] with nitrosyl salts NO+X- (X = BF4, PF6, SbF6) in acetonitrile at -20 °C give the blue nitrosyl compounds {(0N)Pt [xxx] X·nCH3CN. Nitrosation at the amino group is not observed. The spectroscopic data of the nitrosyl complexes (IR, XPE) are reported. [xxx] + PF6 - reacts with lithium halides or halogens in DMF to give the platinum (IV) complexes X2Pt(NH2CH2CO2)2 (X = CI, Br, I).
