摘要: Metal Complexes of Biologically Important Ligands, CLVII [1] Halfsandwich Isocyanoacetylamino acid esters and Isocyanoacetyldi- tripeptide („Isocyanopeptides”) N-Isocyanoacetyl-amino CNCH2C(O) NHCH(R)CO2CH3 (R = CH3, CH(CH3)2, CH2CH(CH3)2, CH2C6H5) N-isocyanoacetyl-di- CNCH2C(O)NHCH(R1)C(O)NHCH(R2)CO2C2H5 CNCH2C(O)NHCH(R1)C(O)NHCH (R2)C(O)NHCH(R3)CO2CH3 (R1 R2 R3 CH2C6H5, H, are available by condensation potassium isocyanoacetate with amino or peptide esters. These isocyanides form chloro-bridged complexes [(arene)M(Cl)(μ-Cl)]2 (arene Cp*, p-cymene, M Ir, Rh, Ru) in the presence Ag[BF4] Ag[CF3SO3] cationic halfsandwich [(arene)M(isocyanide)3]+X− (X BF4, CF3SO3).
