Direct reaction between [Cr(CO)6] and arenes with ionic substituents affords the corresponding arene-chromium tricarbonyl complexes, [Cr(CO)3(arene)], in only modest yield. In contrast, these complexes can be prepared in pure form in ...
The chloro-bridged complexes [CpMCl2]2 (Cp = C5Me5, M = Ir, Rh), [(p-cymene)RuCl2]2, [(C6Me6)RuCl2]2 and [(PEt3)PdCl2]2 react with SAMP by cleavage of the chloro bridges to give the corresponding monomeric h1-SAMP complexes. The x-ray structural detns. o ...
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 ...
Organometallic ruthenium(II)-arene complexes are currently attracting increasing interest as anticancer compds. with the potential to overcome drawbacks of traditional drugs like cisplatin with respect to resistance, selectivity, and toxicity. Rational des ...
The trinuclear Ru complexes [RuCl2(PAd2Bu)]3 (1) and [RuCl2(PtBu2Cy)]3 (2) were obtained by reaction of [(p-cymene)RuCl2]2 with 2 equiv of the resp. sterically demanding phosphine. Crystallog. analyses of 1 and 2 show that the three metal fragments are con ...
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 invention relates to a novel class of ligands, complexes comprising such ligands and a metal ion, and adducts of these metal complexes and a macromolecule. Pharmaceutical compositions and methods of making and using the ligand-metal complexes are also ...
In the presence of moderately strong acids in MeCN, Co complexes with BF2-bridged diglyoxime ligands are active catalysts for the redn. of protons to H2 at potentials as pos. as -0.28 V vs. SCE. [on SciFinder (R)] ...
The reaction of (arene)RuCl2 (arene = cymene, 1,3,5-C6H3Me3) and Cp*RhCl2 half-sandwich complexes with tridentate heterocyclic ligands in the presence of base has been investigated. In all cases, the chloro-ligands were substituted to give metall ...
A method for the facile prepn. of oligoribonucleotide analogs contg. b-D-allo-furanosyl nucleosides with addnl. functional groups tethered to the 6'-O positions is presented. It is based on the synthesis in two protected nucleosides carrying a 6'-O-bromope ...
