Supramolecular assembly of linear trinickel complexes incorporating metalloporphyrins: A novel one-dimensional polymer and oligomer

One-dimensional polymeric or oligomeric chains, in which various linear trinickel complexes linked to the axial sites of metalloporphyrins by the combination of self-assembly and coordination chemistry, have been constructed. A carboxylate group of carboxylpyridine was attached to the end of linear trinickel complexes to produce the linear building blocks, Ni 3(dpa)4X2 [X = 4-PyCOO- (1) or 3-PyCOO- (2)], which was then reacted with metalloporphyrins to form stable polymers or oligomers. The new self-assembled oligomeric chain, [Ni 3(dpa)4(4-PyCOO)2][ZnTPP]2 (3), and two novel self-assembled one-dimensional polymeric chains, {[Ni 3(dpa)4(4-PyCOO)2[MnTPP]}n(ClO 4)n (4), and {[Ni3(dpa)4(3-PyCOO) 2][MnTPP]}n(ClO4)n (5), [dpa – = di(alpha-pyridyl)amido anion; TPP = meso-tetraphenyl- porphyrinato dianion], have been synthesized and their structures were determined by X-ray diffraction. The UV/vis spectra indicate the absence of any noticeable interactions between the linear trinickel units and metalloporphyrins in these chains. The magnetic susceptibility measurements in the solid state show that both polymers 4 and 5 have a very weak ferromagnetic interaction. The Royal Society of Chemistry 2003.

Synthesis of cyclosal-(glycopyranosyl-6)-phosphates as activated sugar phosphates

The synthesis of cycloSal-masked glycopyranosyl phosphates demands suitably protected precursors. A highly regioselective strategy for the preparation of cycloSal-(1,2,3,4-tetra-O-acetylglycopyranosyl-6)-phosphates was developed. Intermediate introduction of the Fmoc-group allowed the isolation of the 1,2,3,4-tetra-O-acetyl glycopyranoses to be skipped, thus, no isomerization occurred. Glycopyranoses were first converted into the 6-O-TBDMS-1,2,3,4-tetra- O-acetyl derivatives then, in a one-pot reaction, the silyl ether was cleaved and the resulting 1,2,3,4-tetra-O-acetyl glycopyranoses were trapped with Fmoc-chloride. In this exchange of protecting groups no acetyl group migration occurred. The 6-O-Fmoc-protected intermediates were selectively converted into the cycloSal-masked glycopyranosyl phosphates in a one-pot reaction. Finally, the reactivity of these activated glycopyranosyl-6-phosphates was demonstrated in the synthesis of 1,6-diglycopyranosyl-phosphates. The preparation of 6-Fmoc-protected glycopyranoses succeeded with up to 83 % yield starting from the corresponding glycopyranoses. With this strategy, the migration of acetyl groups can be avoided and the acceptor-substituted cycloSal phosphate triesters were prepared regioselectively. These activated glycopyranosyl-6-phosphates can be used in coupling reactions with nucleophiles. Copyright

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.

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.

Design, synthesis and in vitro evaluation of d-glucose-based cationic glycolipids for gene delivery

A cationic lipid consists of a hydrophilic headgroup, backbone and hydrophobic tails which have an immense influence on the transfection efficiency of the lipid. In this paper, two novel series of cationic cyclic glycolipids with a quaternary ammonium headgroup and different-length hydrophobic tails (dodecyl, tetradecyl, hexadecyl) have been designed and synthesized for gene delivery. One contains lipids 1-3 with two hydrophobic alkyl chains linked to the glucose ring directly via an ether link. The other contains lipids 4-6 with two hydrophobic chains on the positively charged nitrogen atoms. All of the lipids were characterized for their ability to bind to DNA, size, zeta-potential, and toxicity. Atomic force microscopy showed that the lipids and DNA-lipid complexes were sphere-like forms. The lipids were used to transfer enhanced green fluorescent protein (EGFP-C3) to HEK293 cells without a helper lipid, the results indicated that lipids 4-6 have better transfection efficiency, in particular lipids 5-6 have similar or better efficiency, compared with the commercial transfection reagent lipofectamine 2000.
