The condensation of aryl boronic acids with 2,3-dihydroxypyridine gives boronates, which self-assemble to form tetrameric macrocycles as evidenced by X-ray crystallographic analyses. ...
New methods that allow the generation of transition metal-based catalysts and receptors are discussed. It is shown that heterobimetallic, halogeno-bridged complexes are well-suited for screening assays in combinatorial catalysis. Metal catalysts with a str ...
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 ...
The reaction of half-sandwich complexes of ruthenium, rhodium, and iridium with amino-substituted 3-hydroxy-2-pyridone ligands in aqueous solution gives monomeric O,O'-chelate complexes. Upon addition of base, the complexes assemble to form trimeric metall ...
Numerical simulations are presented that describe the adaptive behavior of simple dynamic combinatorial libraries (DCLs) upon addition of a target. By studying the effect of various parameters such as the network topology, the initial concentrations, the a ...
The trinuclear arene-ruthenium cluster cation, Ru3H3(O)(C10H14)2(C14H16O4), has been synthesized and crystallized as the tetrafluoroborate (BF4-) salt. The cations form, along the b axis, infinite one-dimensional chains through pi-stacking interaction ...
The reaction of [RuCl3(AsPh3)(2)(MeOH)] with the dimeric complexes (cod)RhCl, (ppy)RhCl (ppy = cyclometalated 2-phenylpyridine), (cymene)RuCl2 and CP*MCl2 (M = Rh, Ir) has been investigated. The structure of the resulting products was s ...
Methods for the synthesis of bimetallic complexes in which two different metal fragments are connected by three chloro or bromo bridges are reported. The reactions are general, fast, and give rise to structurally defined products in quantitative yields. Th ...
The reaction of [ReBr3(CO)(3)]NEt4 with 3-hydroxy-1,2,3-benzotriazine-4 (3 H) -one in the presence of base gave the ionic rhenium complex [ReBr(C7H4N3O2)(CO)(3)][NEt4] (2) which was crystallographically characterized. A neutral metallamacrocycle 3 was ...
A heterobimetallic complex, in which a RuCl2(acetone) (PPh3)(2) fragment is connected via three chloro bridges to a (eta(4)-C4Ph4CO)RhCl fragment, has been identified as a potent catalyst precursor for the Oppenauer-type oxidation of alcohols. With 0.1-0.5 ...
