Supported palladium nanoparticles on hybrid mesoporous silica: Structure/activity-relationship in the aerobic alcohol oxidation using supercritical carbon dioxide

The preparation, characterization, and catalytic properties of Pd nanoparticles supported on mesoporous organic-inorganic hybrid materials are described for continuous-flow aerobic oxidation of alcohols using supercritical carbon dioxide (scCO2) as a mobile phase. The nanoparticles were generated “bottom-up” from molecular precursors that were precoordinated to the support through suitable anchor units. The most active material allows high single-pass conversions in scCO2 at temperatures as low as 60 C. This high activity may be associated with the presence of small primary crystallites (approx. 2 nm) that conglomerate to ensembles about 25 nm in size, leading to a larger number of high-indexed planes in small volume units. These findings may provide useful guidelines for further catalyst design on the nanoscale for green oxidation methods.

High spin ground state copper(II) and nickel(II) complexes possessing the 3,5-di-tert-butyl-1,2-semiquinonate radical anion

Several high spin ground-state compounds based upon ferromagnetic coupling between a metal ion and the chelating 3,5-di-tert-butyl-1,2-semiquinonate radical anion, [DTBSQ][rad]?, as they possess unpaired electron spins in orthogonal dx2?y2/dz2 and pi? orbitals, are described. [CuII(DPyA)(DTBSQ)](ClO4) (DPyA?=?2,2?-dipyridylamine) was reinvestigated and its singlet excited state is 282?cm?1 [0.035?eV; J/kB?=?406?K (H?=??JSa¡¤Sb)] above the triplet ground state. [CuII(bipy)(DBCat)(MeOH)] (bipy?=?2,2-bipyridine; DBCat?=?3,5-di-tert-butylcatecholate), [CuII(bipy)(DTBSQ)](BF4), [CuII(DPyA)(DTBSQ)-(THF)2](BF4) and [NiII(DPyA)(DTBSQ)(THF)2](BF4) have been structurally characterized and have high spin ground states whose low spin excited states lie 28?cm?1 (0.0034?eV), 382?cm?1 (0.047?eV), 335?cm?1 (0.042?eV), and 108?cm?1 (0.013?eV) higher, respectively. The triplet-singlet separation is 18% greater for [CuII(DPyA)(DTBSQ)(THF)2]+ than [CuII(DPyA)(DTBSQ)]+ and is ascribed to greater orthogonality of the CuII dx2?y2/dz2 and [DTBSQ][rad]? pi? orbitals for octahedral [Cu(DPyA)(DTBSQ)(THF)2]+ with respect to distorted square pyramidal structure of [Cu(DPyA)(DTBSQ)]+. This greater energy of the excited state correlates with the shorter than average M-ODTBSQ distance, i.e. [Cu(bipy)(DTBSQ)]+?>?[CuII(DPyA)(DTBSQ)(THF)2]+?>?[Ni(DPyA)(DTBSQ)(THF)2]+. The order of magnitude lower value for [CuII(bipy)(DBCat)(MeOH)] arises from a weak intradimer S?=?1/2 Cu(II) interaction, not via ferromagnetic coupling between the S?=?1/2 Cu(II) and [DTBSQ][rad]? sites.

Reductive acylamination of pyridine N-oxide with aminopyridines and their N-p-tolylsulfonyl derivatives

Pyridine N-oxide reacts with 2- and 3-aminopyridines and their N-p-tolylsulfonyl derivatives in alkaline medium in the presence of p-toluenesulfonyl chloride to give N-p-tolylsulfonyl-2,2?- and 2,3?-dipyridylamines, respectively, as a result of reductive acylamination. In the reactions with 4-aminopyridine and 4-p-tolylsulfonyl- aminopyridine, their N-p-tolylsulfonyl- and N,N-bis(p-tolylsulfonyl) derivatives are formed, while reductive acylamination does not occur. 2005 Pleiades Publishing, Inc.

Molecular magnetism, quo vadis? A historical perspective from a coordination chemist viewpoint?

Molecular magnetism has travelled a long way from the pioneering studies on electron exchange and double exchange or spin crossover and valence tautomerism in small oligonuclear complexes, from mono- to di- and tetranuclear species, to the current investigations about magnetic anisotropy and spin dynamics or quantum coherence of simple mono- or large polynuclear complexes, behaving as switchable bistable molecular nanomagnets for potential applications in information data storage and processing. In this review, we focus on the origin and development of the research in the field of molecular magnetism from a coordination chemistry viewpoint, which dates back to the establishment of magnetochemistry as a novel discipline among the molecular sciences. This overview is conceived as an attempt to orientate coordination chemists regarding their role in the future direction that molecular magnetism will undergo in its further evolution toward molecular spintronics and quantum computation. A particular emphasis will be given to some selected recent advances in single-molecule spintronic circuitry and quantum computing devices based on the large class of multiresponsive and multifunctional magnetic metal complexes to stimulate the progress in the field of molecular magnetism.

Synthesis, characterization, mixed-ligand complex formation reactions, and equilibrium studies of Co(II) with 2,2?-dipyridylamine and some selected biorelevant ligands

Binary and ternary cobalt(II) complexes involving 2,2?-dipyridylamine and various biologically relevant ligands containing different functional groups are investigated. The ligands used are dicarboxylic acids, amino acids, and DNA unit constituents. The ternary complexes are formed by simultaneous reactions. The results showed the formation of 1:1 complexes with amino acids and dicarboxylic acids. The effect of chelate ring size of the dicarboxylic acid complexes on their stability constants was examined. The stability of ternary complexes formed with dicarboxylic acids was quantitatively compared with their corresponding binary complexes in terms of the a?log 10 K parameters. The concentration distribution of the complexes in solution was evaluated. The solid complexes of Co(II) dipyridylamine cyclobutane-1,1-dicarboxylate, or malonate, oxalate, and succinate have been synthesized and characterized by elemental analysis, infrared spectra, magnetic, and conductance measurements. Spectroscopic studies and M eff values suggest a tetrahedral geometry for the cobalt(II) complexes. The effect of temperature on the formation constant of the complexes was studied, and the thermodynamic parameters were calculated. Formation of the metal complexes has been found to be spontaneous, exothermic, and entropically favorable.

Synthesis, DNA binding profile and DNA cleavage pathway of divalent metal complexes

Complexes of dipyridylamine based ligand with an anthracene moiety containing divalent metal ions Co(ii), Cu(ii), Ni(ii), Zn(ii) and Cd(ii) were characterized structurally. The experimental results showed that they can induce considerable oxidative DNA cleavage in the presence of hydrogen peroxide and dioxygen. The Zn(ii) complex did not show any appreciable cleavage activity, whereas the Cd(ii) and Ni(ii) complexes were moderately active. On the other hand, Cu(ii) and Co(ii) complex showed the formation of a significant quantity of linear DNA resulting from the double-strand breaks. Mechanistic studies revealed the involvement of HO? and the superoxide anion to be the reactive species in the scission process in aerobic media. A mechanism involving either the Fenton or the Haber-Weiss reaction was proposed for the DNA cleavage mediated by these complexes. The Cu(ii) complex could also cleave the double stranded calf thymus DNA (ds DNA) in the presence of activators, most likely via an oxidative mechanism, whereas the activity of the other complexes was negligible under similar reaction conditions. The kinetic aspects of ds DNA cleavage with the Cu(ii) are detailed. The interaction of the five metal complexes with ds DNA was investigated by UV absorption and linear dichroism studies, and the mode of complexes binding to ds DNA is proposed.

Supramolecular architecture of a copper(II) complex with lactato and 2,2?-dipyridylamine showing embedded water chains

A new mixed-ligand complex [CuL2(dipyam)]-3H2O (1) (L = lactato and dipyam = 2,2?-dipyridylamine) has been prepared and structurally characterized by X-ray diffraction. The presence of three crystallization water molecules creates several hydrogen-bonded networks. Two crystallographic unique crystallization water molecules are arranged into infinite one-dimensional chains embedded by additional hydrogen bonds between stacked complex double-chains, but the third crystallization water molecule is apart from the chain and acts as bridge to form centrosymmetric complex tetramers.
