Tris(2-isocyanocarbonsäureester)-Halbsandwich-Komplexe [(Aren)M(CNCHR1CO2R2)3]2+ (M = Ru, Rh, Ir) / Tris(2-isocyanocarboxylic Acid Ester) – Halfsandwich Complexes [(arene)M(CNCHR1CO2R2)3]2+ (M = Ru, Rh, Ir)

Abstract

By reaction of chloro bridged halfsandwich complexes with silver salts and subsequent addition of isocyanocarboxylic acid esters the isocyanide complexes [(arene)M(CNCHR1CO2R2)3]2+(X−)2 (arene = C6Me6, p-cymene, M = Ru; arene = C5Me5, M = Rh, Ir), (R1 = H, Me, CHMe2, CH2Ph, X = BF4, CF3 SO3) were prepared and characterized. The structure of [(C5Me5) Ir(CNCH2CO2Et)3]2+(CF3SO3−)2 was determined by X-ray structure analysis.
