Metal Complexes of Biologically Important Ligands. XCV. η5-Pentamethylcyclopentadienyl Rhodium, Iridium, η6- Benzene Ruthenium, and Phosphine Palladium Complexes of Proline Methylester and Proline AmideProline methylester (L1) and proline amide (L2) give with the chloro bridged complexes [(η5 -C5Me5)MCl2]2 (M = Rh, Ir), [(η6 -benzene)RuCl2]2 and [Et3PPdCl2]2 N and N,O coordinated compounds: (η5 -C5Me5)M(Cl2)L1 (1, 2 M = Rh, Ir), [(η5-C5Me5) Rh(Cl)(L2)]+Cl- (5), [(η6- C6Me6) Ru(Cl)(L2)]+Cl- (6), [(η6-p-cymene)Ru(Cl)(L2)]+Cl- (7), [(eta;5-C5Me5)M(Cl)(L2-H+)] (9, 10 M = Rh, Ir), (Et3P)Pd(Cl)2L1 (3), and [(Et3P)Pd(Cl)(L2)]+Cl- (8). The NMR spectra indicate that for 5 and 6 only one diastereoisomer is formed. The complexes 1, 2, 3 and 5 were characterized by X-ray diffraction.
Notes:
Prolinmethylester (L1) und Prolinamid (L2) bilden mit den chlorverbrückten Komplexen [(η5-C5Me5)MCl2]2 (M = Rh, Ir), [(η6-p-Cymol)RuCl2]2 und [Et3PPdCl2]2 Verbindungen mit N- und N,O-Koordination: (η5-C5Me5)M(Cl2)L1 (1, 2 M = Rh, Ir), [(η5-C5Me5) Rh(Cl) (L2)]+Cl- (5), [(η6- C6Me6)Ru(Cl) (L2)]+Cl- (6), [(η6-p- Cymol)Ru(Cl)(L2)]+Cl- (7), [(η5- C5Me5)M(Cl)(L2-H+)] (9, 10 M = Rh, Ir), (Et3P)Pd(Cl)2L1 (3) und [(Et3P)Pd(Cl)(L2)]+Cl- (8). Die NMR Spektren weisen darauf hin, daß von 5 und 6 jeweils nur ein Diastereoisomeres entsteht. Die Komplexe 1, 2, 3 und 5 wurden durch Röntgenstrukturanalyse charakterisiert.
