The cationic complexes [(η6-arene)Ru(SC5H4NH)3]2+, arene being C6H6 (1), MeC6H5 (2), p-iPrC6H4Me (3) or C6Me6 (4), have been synthesized from the reaction of 4-pyridinethiol with the corresponding precursor (η6-arene)2Ru2(μ2-Cl)2Cl2 and isolated as the chl ...
This thesis encompasses work on the coordination chemistry and catalytic activity of half sandwich ruthenium(II)-arene phosphine complexes. The investigation of phosphine dissociation and association reactions of these complexes represents the unifying the ...
The title compound, Co(C20H23N3O2)(C5H11N) or [Co{(Me-sal)(2)dien}(pprdn)] BPh4, where (Me-sal) 2dien is 2,2'[1,1'-(3-azapentane-1,5-diyldinitrilo)diethylidyne]diphenolate and pprdn is piperidine, contains a pentadentate (Me-sal) 2dien ligand fu ...
Organometallic ruthenium(II)-arene (RA) antitumour compounds of the general type [Ru(II)(η6-arene)(X)2(pta)], RA-pta, and [Ru(II)(η6-arene)X(en)], RA-en, (X=leaving group; pta=1,3,5-triaza-7-phosphaadamantane, en=ethylenediamine) have been investigated com ...
Some nonenzymic epoxide-initiated polyolefin cyclisations are reported. The presented molecules are partially constrained analogues of (3S)-oxidosqualene, the natural substrate to many important cyclase enzymes. These model compounds feature a preformed C- ...
The present invention relates to organometallic compounds useful in the treatment of metastasis. The organometallic compounds comprise a ligand that is convalently bound to a bioactive compound, which is an inhibitor of a resistance pathway or a derivative ...
The water-sol. ruthenium(II) complexes [Cp'RuX(PTA)2]Y and [CpRuCl(PPh3)(mPTA)]OTf (Cp' = Cp, Cp*, X = Cl and Y = nil; or X = MeCN and Y = PF6; PTA = 1,3,5-triaza-7-phosphaadamantane; mPTA = 1-methyl-1,3,5-triaza-7-phosphaadamantane) were used as catalyst ...
Bis-phosphine Ru(II)-arene complexes are highly active and chemoselective catalysts for the hydrogenation of aldehydes in the presence of olefinic bonds. Mechanistic studies, including comparisons with a structural analog, reactions of an isolated hydride ...
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] ...
A combined d. functional theory/continuum electrostatics approach was used to est. the pKa values of metal-based compds. and their hydrolysis products. Specifically, the protonation states and abs. pKa values of [M(h6-arene)(X)(Y)(pta)]n+ (M = Ru or Os; ar ...
