Heterobimetallic complexes where half-sandwich complexes of ruthenium(II), rhodium(III) and iridium(III) are connected by three bromo-bridges to Re(CO)3 have been prepd. from metathesis reactions of [RuBr(m-Br)(h6-arene)]2 (arene = C6H6, C6H3Et3-1,3,5 or p ...
The 1,1-ethene dithiolato ligands (dithioylidene barbituric acids) react with L2MCl2 [M = Pd, Pt; L = PEt3, PBu3, 1/2 dppe, 1/2 (-)-DIOP, 1/2 2,9-di-Me phenanthroline] to give the 1,1-ethene dithiolato metal complexes L2M[S2C:cycloCC(O)NR1C(O)NR2C]. I ...
Homo- and heterobimetallic complexes, in which half-sandwich complexes of ruthenium(II), rhodium(III), and iridium(III) are connected via three chloro bridges to RuCl2(PPh3)2, have been synthesized. The complexes were obtained in quant. yields by reaction ...
Ru(II) and Os(II) p-cymene dichloride complexes with either a pta (1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane) or [pta-Me]Cl ligand which exhibit anticancer activity were prepd. and characterized by 1H and 31P NMR spectroscopy and mass spectrometry. Thr ...
Three immobilized Cu(II) complexes were generated by the following: (a) homopolymerization of the N,N',N '' chelate ligand tris[2-(1-vinylimidazolyl)]phosphine (1) and subsequent metalation with CuCl2; (b) copolymerization of 1 with ethyleneglycol dimethac ...
The ligand N,N'-bis[6-carboxy-2-pyridylmethyl]ethylenediamine-N,N'-diacetic acid (H4bpeda) was synthesized using an improved procedure which requires a reduced no. of steps and leads to a higher yield with respect to the published procedure. It was obtaine ...
Highly reactive tris-carbene Co(I) complexes [(TIMENaryl)Co]Cl react with org. azides to yield monomeric Co(III) imido complexes (TIMENaryl)Co(NAr') (aryl = mes, xyl; Ar = -C6H4-CH3, -C6H4-OCH3). The cobalt-imido fragment in these complexes is elec ...
Solutions of the strong complexing agent ethylenediaminetetraacetic acid (EDTA) and Cu, Pb, Cd, Al, and Fe(III) were examined by electrospray mass spectrometry (ES/MS). Uncomplexed EDTA and metal-EDTA complexes survive the electrospray process intact and c ...
Metal Complexes of Biologically Important Ligands, LXX[1].- Synthesis, Stereochemistry and Reactions of Ruthenium(II) and Osmium(II) Complexes with -Amino Carboxylates. The reactions of MHCl(CO)(PPh3)3 with salts of -amino acids give the hydrido-N,O-chelat ...
