The circular dichroism spectra of a variety of vic-amino alcohols in the presence of dirhodium tetraacetate as an auxiliary chromophore were measured in ethanol as the solvent. The method was tested with several model compounds, representing both acyclic and cyclic amino alcohols, including biologically important adrenergic drugs as well as amino sugars. The study demonstrated that the sign of the Cotton effects is determined by the preferred helicity of the O-C-C-N unit in the chiral complex formed in situ. The combined analysis of the CD, UV-vis, 1H and 13C NMR indicated predisposition to form chiral complexes by initial coordination of the amino alcohol at the axial coordination site followed by migration to the equatorial position. Finally, after migration of the ligand to an equatorial position(s) a bridging or a chelating complex is formed. Hence, vic-amino alcohols in ethanol act as bidentate ligands in the end.

Guanidine derived six-membered [C,N] palladacycles of the types [(C,N)Pd(mu-OC(O)R)]2 (1a-d), [(C,N)Pd(mu-Br)]2 (2a,b), cis-[(C,N)PdBr(L)] (3a-d, 4, and 5), and ring contracted guanidine derived five-membered [C,N] palladacycle, [(C,N)PdBr(CNXy)] (6) were prepared in high yield following the established methods with a view aimed at understanding the influence of the substituents on the aryl rings of the guanidine upon the solid state structure and solution behaviour of palladacycles. Palladacycles were characterised by microanalytical, IR, NMR and mass spectral data. The molecular structures of 1a, 1c, 2a, 2b, 3a, 3c, 3d, and 4-6 were determined by single crystal X-ray diffraction data. Palladacycles 1a and 1c were shown to exist as a dimer in transoid in-in conformation in the solid state but as a mixture of a dimer in major proportion and a monomer (kappa2-O, O?-OAc) in solution as deduced from 1H NMR data. Palladacycles 2a and 2b were shown to exist as a dimer in transoid conformation in the solid state but the former was shown to exist as a mixture of a dimer and presumably a trimer in solution as revealed by a variable temperature 1H NMR data in conjunction with ESI-MS data. The cis configuration around the palladium atom in 3a, 3c, and 3d was ascribed to steric influence of the aryl moiety of NAr unit and that in 4-6 was ascribed to antisymbiosis. The solution behaviour of 3d was studied by a variable concentration (VC) 1H NMR data.

The synthesis, characterization, DNA interaction and antiproliferative behavior of new pi-arene ruthenium(II) piano-stool complexes with nitrogen ligands are described. Three series of organometallic compounds of formulae [RuCl2(eta6-p-cym)L] were synthesized (with L = 2-, 3- or 4-methylpyridine; L = 2,3-, 2,4-, 2,5-, 3,4-, 3,5-dimethylpyridine and L = 1,2-, 1,3- 1,4-methylaminobenzene). The crystal structures of [RuCl 2(p-cym)(4-methylpyridine)], [RuCl2(p-cym)(3,4- dimethylpyridine)] and [RuCl2(p-cym)(1,4-methylaminobenzene)] were resolved and the characterization was completed by spectroscopic UV-vis, FT-IR and 1H NMR studies. Electrochemical experiments were performed by cyclic voltammetry to estimate the redox potential of the Ru(II)/Ru(III) couple. The interaction with plasmid pBR322 DNA was studied through the examination of the electrophoretical mobility and atomic force microscopy, and interaction with ct-DNA by circular dichroism, viscosity measurements and fluorescence studies based on the DNA-ethidium bromide complex. The antiproliferative behavior of the series with L = methylpyridine was assayed against two tumor cell lines, i.e. LoVo and MiaPaca. The results revealed a moderate cytotoxicity with a higher activity for the LoVo cell line compared to the MiaPaca one.

The relationship between the structure of the side chain of pyridine derivatives and the inhibitory potency towards thromboxane synthetase was quantitatively analyzed by the adaptive least-squares (ALS) method. The main descriptors concerning the molecular structure used in the analysis were estimated on the basis of the minimum energy conformation obtained from MINDO/3 molecular orbital calculation. All of 27 pyridine derivatives were recognized correctly by the best discriminant function. Validity of the discriminant function was tested by the leave-one-out technique. The activity ratings of 23 compounds could be predicted correctly with the descriptors used in the best function. Application of this relationship to the design of inhibitors and the mode of enzyme-inhibitor interaction were discussed.

These examples are the first of isolable Cu-carbene complexes that react with alkenes to give cyclopropanes. Furthermore, electron-rich, bidentate N,N-donor ligands can be designed to impart stereo- and enantio-selectivity in the cyclopropanation of alkenes with diazoalkanes.

Although visible light photoredox catalysis has emerged as a powerful tool for the construction of C-C bonds, common catalysts and/or their photoexcited states suffer from low redox potentials, limiting their applicability to alkyl radical generation from substrates with activated carbon-halogen bonds. Radicals derived from these activated compounds, being highly electrophilic or stabilized, do not undergo efficient addition to heteroarenes. Herein we describe the photocatalytic generation of nucleophilic alkyl radicals from unactivated bromoalkanes as part of a universal and efficient cross-coupling strategy for the direct alkylation of heteroarenes using a dimeric gold(i) photoredox catalyst, [Au2(bis(diphenylphosphino)methane)2]Cl2. The method proves to be efficient for alkylation of arenes under mild conditions in the absence of directing groups.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons.
