Metal Complexes with Biologically Important Ligands, XLVII1). Copper, Nickel, Palladium, and Platinum(II) Complexes of C-Allylglycine and N-(Diphenylmethylene)-C-allylglycine EsterC-Allylglycine reacts with Ni, Cu, Pd, and Pt(II) salts - dependent on pH - to give trans-N,O-bischelate complexes M[NH2CH(CH2CH=CH2CO2]2 (M = Cu, Ni, Pd) 1 or N,η2-C,C-chelate complexes Cl2MNH2CH(CO)2R)CH2CR=CH2 (R = H, Me; M = Pd, Pt). The reactions of N-(diphenylmethylene)-C-allylglycine ester with Na2PdCl4 and PtCl2 yield ortho-metallated complexes 3, in which the ligand is bound to the ortho-C(phenyl) atom, the imino-B atom, and the olefinic double bond. 2a and 3c were characterized by X-ray structure analyses.
Notes:
C-Allylglycin reagiert - abhängig vom pH-Wert - mit Ni-, Cu-, Pd- und Pt(II)-Salzen zu den trans-N,O-Bischelat-Komplexen M[NH2CH(CH2CH=CH2CO2]2 1 (M = Cu, Ni, Pd) oder zu N,η2-C,C-Chelat-Komplexen Cl2MNH2CH(CO)2R)CH2C-(R)=CH2 2 (R = H, Me; M = Pd, Pt). N-(Diphenylmethylen)-C-allylglycinester setzen sich mit Na2PdCl4 oder PtCl2 zu den ortho-metallierten Komplexen 3 um, in denen der Ligand dreizähnig über das ortho-C(Phenyl)-Atom, das Iminostickstoff-Atom und die C = C-Doppelbindung koordiniert ist. Die Molekülstrukturen von 2a und 3c wurden röntgenographisch bestimmt.
