 Title    2.3-Dihydro-2-methoxyethylimino-l,3-dimethylimidazol -ein neuer hemilabil koordinierender Chelatligand [1] 2.3-Dihydro-2-methoxyethylimino-\ ,3-dimethylimidazole -a Novel Hemilabile Coordinating Chelate Ligand [1]  
 Abstract    The bifunctional 2,3-dihydro-2-methoxyethylimino-l,3-dimethylimidazole (C8H 15N30 , 10) is obtained from the reaction of methoxyethyl tosylate (7) and 2,3-dihydro-2-imino-l,3-dimethylimidazole (8) followed by deprotonation in good yield. 10 reacts with {(COD)RhCl}2 (COD = 1,5-cyclooctadiene) to give the imine complex (C8H 15N30)Rh(C0D)Cl (11), which is converted into the chelate complex [(C8H 15N30)Rh(C0D)]BF4 (12) on treatment with AgBF4. The imine complex (C8H 15N30) 2PdCl2 (13) is formed through the reaction of 10 with (PhCN)2PdCl2. The X-ray structures of 11, 13 and 2 C8H 15N30 • H2PdCl4 (15) are reported. R R 1 Rv -■

 Abstract    The chloro bridged complexes [(2-phenylpyridine-C,N)2RhCl]2 and [(benzo[h]chinoline-C,N)2RhCl]2 react with the anions of alanine, valine and phenylalanine to give the chiral octahedral N,0-chelates L2Rh(a-aminocarboxylate) (1 -5) as mixtures of two diastereoisomers. The complex (benzo[h]chinoline-C,N)2Rh[(S)-NH2CH(CH3)C 0 2-N,0] was characterized by X-ray diffraction. Its crystals contain two diastereoisomers in the unit cell.

 Abstract    The crystal structure determination of the new rhodium(III)-complex [(DM L)(C5Me5)ClRh](PF6). DML = 1,3-dimethyllumazine, reveals 0 4,N5 coordination of the metal to DML with not very different bond lengths of 213.0(2) pm (R h -N) and 219.2(2) pm (R h -O). This result stands in contrast to the previously reported structure of a cationic dihydrobiopterin bound to [Mo(0)C13] which exhibited a very unsymmetrical chelate ar­ rangement. Chemical and electrochemical two-electron reduction of the Rh(III) complex led to a very labile Rh(I) species (DM L)(C5Me5)Rh which is distinguished by an intense charge transfer band in the visible. The results confirm the characterization of DML as a weak o donor In acceptor ligand with a rather low-lying tc* orbital.

 Title    Metallkomplexe mit biologisch wichtigen Liganden, C IX [1]. Metallorganische Verbindungen von Platin(II), Ruthenium(II), Rhodium (III) und Iridium (III) mit Oxocarbonyl-N-geschützten a-Am inosäuren und L-Methionylglycinat Metal Complexes with Biologically Important Ligands, CIX [1]. Organometallic Compounds o f Platinum(II), Ruthenium(II), Rhodium(III), and Iridium(III) with Oxocarbonyl-N-protected a-Amino Acids and L-Methionylglycinate  
 Abstract    The reaction o f m -(P h 3P)2PtCl2 with BOC-N-glycine and FMOC-N-alanine gives the carboxylate coordinated complexes as-(Ph3P)2Pt(Cl)(0 2CCH2N HB0 C) (1) and cis-(Ph3P)2Pt(C l)(02C C (H)(M e)N H FM 0C (2). Chloride and proton abstraction from 1 affords the N,Ö-chelate complex (Ph3P)2 P t(0 2C CH2N B 0C) (3). From the chloro-bridged compounds [Cp*MCl2] 2 (M = Rh, Ir), [(/?-cymene)RuCl2] 2 and BOC-N-L-MetGlyOH (L) the compounds Cp*M (Clj2L (4, 5) and (/?-cymene)Ru(Cl)2L (6) with the mono-dentate dipeptide are obtained which in the presence o f NaOMe form Ö,N,S-bis(chelate) complexes 7 -9 . The X-ray dif­ fraction analysis of the iridium 0,N,S chelate complex 8 shows a five membered and a seven membered chelate ring.

Of these compounds, the mesitylrhodium complex Rh(2,4,6-Me3C6H2)(CO)(PPh3)2 as well as the iridium and rhodium alkyls with Me3SiCH2 and Me3CCH2 ligands show cis,irans-isomerism which is demonstrated on the basis of infrared and NMR spectroscopic evidence.

 Title    Enantioselective Catalysis, XVII [1], Enantioselective Catalytic Hydrogenation of Unfunctionalized Ketones  
 Abstract    Three diastereomeric rhodium bisphosphane complexes have been applied to asymmetric hydrogenation of unfunctionalized, non-chelating aliphatic and aromatic ketones. The ee values o f the catalysis products differ considerably for the diastereomerical catalysts. 70% ee were obtained in hydrogenating butyrophenone, and 83.7% ee for pinacoline. The results depend strongly on the solvent used.
