A series of ruthenium, osmium and rhodium complexes utilizing pta, (1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decane) and pta-Me+, its N-methyl derivative, have been synthesized. Their characterization by 1H and 31P NMR spectroscopy, ESI-MS and single crysta ...
The silver, copper and gold complexes of tripodal N-heterocyclic carbene (NHC) ligand, 1,1,1-tris[(3-methylimidazol-1-yl-2-ylidene)methyl]ethane were prepd. and characterized. The silver complex of the title ligand, TIMEMe was prepd. by reaction of [H3TIME ...
The in vitro activity of a series of ruthenium clusters, [(η6-C6H6)(η6-C6Me6)2Ru3(μ-H)3(μ3-O)][BF4], [(η6-C6H6)(η6-1,4-iPrC6H4Me)(η6-C6Me6)Ru3(μ-H)3(μ3-O)][BF4], [(η6-C6H6)4Ru4(μ-H)4][BF4]2, [(η6-C6H5Me)4Ru4(μ-H)4][BF4]2 and [(η6-C6H6)4Ru4(μ-H)3(μ-OH)][Cl] ...
Recent advances in the development of ruthenium catalysts for the atom transfer radical addn. of polyhalogenated compds. to olefins ('Kharasch reaction') are described. Three classes of homogeneous catalysts are discussed: halfsandwich complexes with h6-ar ...
A variety of homonuclear and heteronuclear transition metal carbonyl clusters have been analyzed by ultraviolet laser desorption/ionization time-of-flight mass spectrometry. The spectra were recorded in negative and positive ion modes, using both linear an ...
Reaction of the dimer [(η5-C5Me5)RhCl(μ2-Cl)]2 with 2 or 4 equiv of the water-soluble phosphine 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (pta) affords [Rh(η5-C5Me< ...
The reaction of [(η6-p-cymene)RuCl2]2 with some bis(phosphane) ligands (dppm, dppe, dppv, dppa, dpp14b, dppf) has been investigated. In general mixtures of products were obtained, although the pendant phosphane complexes [( ...
C-linked disaccharide derivatives mimicking O-beta-D-galactopyranosyl-(1-->3)-D-galactopyranosides (end groups in Core-B structures of biologically important proteoglycans) have been obtained from isolevoglucosenone and beta-D-galactopyranosylcarbaldehyde ...
T-BuP(NH2)2 reacts with base-stabilized group 13 tri-hydrides with adduct formation (THF-BH3), with redn. to give t-BuPH2 (Me3N-AlH3) and with elimination of H22 and formation of a metallonitridophosphinate (Me3N-GaH3). In contrast, the reaction with Cp*Ti ...
