18-electron ruthenium phosphine sulfonate catalysts for olefin metathesis

The first instances of ruthenium alkylidene complexes based on chelating phosphine sulfonates are presented. Although these complexes are formally 18-electron complexes bearing cis phosphines and cis one-electron donors (sulfonates and chlorides), they are surprisingly active for ring-closing metathesis, cross-metathesis, and ring-opening metathesis polymerization, thus highlighting the unique potential of the sulfonate ligand in the design of a ruthenium metathesis catalyst.

Enantioselective Total Synthesis of Antibiotic CJ-16,264, Synthesis and Biological Evaluation of Designed Analogues, and Discovery of Highly Potent and Simpler Antibacterial Agents

An improved and enantioselective total synthesis of antibiotic CJ-16,264 through a practical kinetic resolution and an iodolactonization reaction to form the iodo pyrrolizidinone fragment of the molecule is described. A series of racemic and enantiopure analogues of CJ-16,264 was designed and synthesized through the developed synthetic technologies and tested against drug-resistant bacterial strains. These studies led to interesting structure-activity relationships and the identification of a number of simpler, and yet equipotent, or even more potent, antibacterial agents than the natural product, thereby setting the foundation for further investigations in the quest for new anti-infective drugs.

Electropolymerisable bipyridine ruthenium(II) complexes: Synthesis, spectroscopic and electrochemical characterisation of 4-((2-thienyl) ethenyl)- and 4,4?-di((2-thienyl) ethenyl)-2,2? -bipyridine ruthenium complexes

Four new ruthenium polypyridyl complexes with mono- or di-((2-thienyl) ethenyl) substituted bipyridines have been synthesized. The complexes were characterized by NMR, elemental analysis, UV-Vis absorption and electrochemistry (differential pulse and cyclic voltammetry). Electroactive polymer films of these complexes have been prepared by oxidative electropolymerisation and characterized by UV-Vis absorption spectroscopy and electrochemistry. The electrochemically induced polymerisation of the complexes resulted in a significant shift of the oxidation potential of the Ru(II)-Ru(III) process towards more positive potentials. Also, MLCT absorption band of the polymeric complexes is shifted towards shorter wavelengths. These results are interpreted in terms of an interruption of the conjugated system of the (2-thienyl)ethenyl-substituted bipyridine ligands due to a radical polymerisation mechanism affecting rather the ethenyl part of the ligand than the thienyl.

Cyclopentadienyl Ruthenium(II) Complex-Mediated Oxidation of Benzylic and Allylic Alcohols to Corresponding Aldehydes

This work reports an efficient method for the oxidation reaction of aliphatic, aromatic allylic, and benzylic alcohols into aldehydes catalyzed by the cyclopentadienyl ruthenium(II) complex (RuCpCl(PPh3)2) with bubbled O2. Through further optimizing controlled studies, the tendency order of oxidation reactivity was determined as follows: benzylic alcohols > aromatic allylic alcohols >> aliphatic alcohols. In addition, this method has several advantages, including a small amount of catalyst (0.5 mol%) and selective application of high discrimination activity of aliphatic, aromatic allylic, and benzylic alcohols.

Alkene oxidation catalyzed by a ruthenium-substituted heteropolyanion, SiRu(L)W11O39: The mechanism of the periodate mediated oxidative cleavage

A ruthenium-substituted heteropolyanion SiRu(H2O)W11O395- was synthesized and characterized. The hydrophobic quaternary ammonium salt of the heteropolyanion ((C6H13)4N)5SiRu III(H2O)W11O39 was used as a catalyst for the oxidation of alkenes with tert-butyl hydroperoxide, potassium persulfate, iodosobenzene, and sodium periodate as primary oxidants. Reactivity and selectivity were found to be dependent on the oxidant used; several different types of oxidation processes could be identified including allylic oxidation, epoxidation, and oxidative cleavage. Use of sodium periodate as oxidant enabled selective bond cleavage with aldehydes as the exclusive product. Different product selectivity and UV-vis and IR spectra of the ruthenium heteropoly compound in the presence of the various oxidants shows that unique mechanisms are operating in each case. A series of further experiments into the oxidation of styrene derivatives to benzaldehydes by sodium periodate including investigation of the reaction kinetics, substituent effects, and isotope incorporation enabled the formulation of a reaction mechanism. The reaction proceeds by interaction of the styrene with the catalyst forming a metallocyclooxetane which rearranges in the rate-determining step to a cyclic diester through two different transition states depending on the ring substituent. In the final step the cyclic diester decomposes yielding the cleavage products.

Ru(iii)-based compounds with sulfur donor ligands: Synthesis, characterization, electrochemical behaviour and anticancer activity

In recent years, Ru(iii) complexes have emerged as a new class of effective anticancer agents against tumors that proved to be resistant to all other chemotherapeutic drugs currently in clinical use. To extend our previous studies on metal complexes containing sulfur-donor ligands, we report here on the synthesis and characterization, by means of several spectroscopic and analytical techniques, some [Ru(RSDT)3] and [Ru2(RSDT) 5]Cl complexes with dithiocarbamato ligands derived from methyl/ethyl/tert-butyl esters of sarcosine. Their electrochemical behaviour was also studied by cyclic voltammetry. All the complexes were tested for their cytotoxicity on a panel of human tumor cell lines showing highly significant antitumor activity. The chemical and biological properties of the newly synthesized complexes, were compared with those of [Ru(DMDT)3] and [Ru2(DMDT)5]Cl species (DMDT = N,N- dimethyldithiocarbamate) whose chemical (not biological) characterization has been already reported in literature.

Electrochemical Reduction of Some Tris(beta-diketonato)ruthenium(III) Complexes in Acetonitrile and Interaction of the Reduced Anions with Lithium and Sodium Ions

In tetraethylammonium perchlorate-acetonitrile solution, (R1,R3= -CH3, -CF3, -C6H5, -C(CH3)3; R2= -H, -C6H5) was reversibly reduced at a dropping mercury electrode to the corresponding univalent anion. A linear relationship was found between the half-wave potential and the sum of the Hammett constants of the substituents of ligands. In some cases, the polarogram and the cyclic voltammogram were shifted to more positive potentials in the presence of lithium or sodium ions. This effect was explained quantitatively by the two-step association between the reduction product, -, and alkali metal ions. The association constants were calculated.The K2 values were appreciable and the K1 values were much larger than expected for a simple electrostatic interaction. Furthermore, the K1 values were linearly related to the sum of the Hammett constants of the substituents of the ligands. These results suggest the importance of the local charge distribution on the complex anions. In the presence of lithium ion, – forms Li which is insoluble in acetonitrile.
