Ab initio analysis of the interaction of CO2 with acetylated d -glucopyranose derivatives

Peracetylated d-glucopyranose has a high solubility in CO2 and can be a promising phase-change physical solvent or absorbent for CO2, as reported recently. However, peracetylated d-glucopyranose is unstable under acidic atmospheres, especially in sulfur-containing waste gases, and the possibly major decomposition products are 2,3,4,6-tetra-O-acetyl-d-glucopyranose, 1-thiol-d-glucopyranose tetraacetate, and 1-mercaptoethyl-d-glucopyranose tetraacetate. Therefore, it is highly interesting to investigate the interaction between CO2 and these three compounds using ab initio calculations, including geometry optimizations with HF/3-21G, B3LYP/6-31+G??and single-point energy calibration with MP2/aug-cc-pVDZ. The results indicate that the electrostatic interactions between the substrates and CO2 are mainly influenced by the interaction distance and the numbers of negative charge donors or the interacting pairs involved in the complex. It is furthermore found that DeltaE increases significantly if S and O atoms could interact with CO2 simultaneously. The binding energy is irrelevant if one considers the chemical environment of the O atom (i.e. OAc, OE or OS) or the S atom (i.e. SEt or SH), and the electronegativity difference between the S and O atoms. The three substrates studied are still excellent CO2-philes, although their average DeltaE (-20kJ/mol) is slightly lower than that of peracetylated d-glucose (-22kJ/mol), which has one more O atom that can interact with CO2. Therefore, the applications of carbohydrates can be expanded to include adsorbents for CO2, SO2 or both, and the functional groups attached to the carbohydrate can vary from those to the acetyl groups.

Adipate as a tetradentate bridging ligand: Synthesis, structure and properties of Cu(II) and Ni(II) compounds with 2,2?-dipyridylamine as a terminal co-ligand

The synthesis, characterization, single crystal structures and physical properties of the compounds [Cu2(dpa)2(adp) 2](H2O)2 (1) and [Ni2(dpa) 2(adp)]Cl2 (2), in which dpa = 2,2?-dipyridylamine; adp = adipate(2-) anion, are presented. In both dinuclear compounds the dpa is chelating bidentately, whereas adipate acts as a tetradentate bridge between the 2 metal ions, using both carboxylate oxygen atoms as a chelate. The Cu(II) compound has 2 bridging adipate dianions, whereas the Ni(II) compound has a single bridging adipate(2-); in the latter case the charge of the dinuclear unit is compensated by 2 lattice chloride anions. The N-H of the dpa donates an intermolecular H bond to neighboring molecules; i.e. to the carboxylates for the Cu compound and to the lattice chlorides for the Ni one. In both compounds the metal ions are in a distorted octahedral geometry, and diffuse reflectance spectra agree with this geometry. The Ni?Ni contact distance is very long (1089.3 pm). The EPR spectrum of the Cu(II) compound shows a broad signal, and no hyperfine signals are resolved; also no spin = 1 signals are seen, which is in agreement with the very long dinuclear Cu?Cu contact distance (831.7 pm). Magnetic susceptibility measurements of the Cu compound down to 5 K show a very weak ferromagnetic coupling with a magnetic moment (per Cu) increasing from 1.73 B.M. (room T) to 1.88 B.M. (at 5 K).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 499-40-1, you can also check out more blogs about499-40-1

Synthesis of Tc-99m labeled glucosamino-Asp-cyclic(Arg-Gly-Asp-d-Phe-Lys) as a potential angiogenesis imaging agent

Angiogenesis imaging agents for single photon emission computed tomography (SPECT) play a role in diagnosing tumor-induced angiogenesis as well as tumor metastasis. We synthesized and evaluated radiolabeled RGD glycopeptides by incorporation of the [99mTc(CO)3(H2O)3] +. 99mTc labeled glucosamino-D-c(RGDfK) ([99mTc]2) was prepared in 90-93% radiochemical yields (decay corrected). In vitro cell binding assays demonstrated selective binding [99mTc]2 to human umbilical vein endothelial (HUVE) cells, with inhibition of binding to 37.3% of control levels by 10 muM of cold authentic compounds. In addition, [99mTc]2 was shown to have high binding affinity to purified alphavbeta3 integrin (IC50 = 1.5 nM). These results suggest that these radiolabeled RGD glycopeptides may have value for non-invasive assessment of angiogenesis.

I2/ionic liquid as a highly efficient catalyst for per-O-acetylation of sugar under microwave irradiation

A practical and highly efficient approach was developed to synthesize peracetylated sugar derivatives using a recyclable iodine/PEG400-based ionic liquid catalyst (I2/IL). The peracetylated sugars were readily obtained in a few minutes in excellent yields (90%-99%, 13 examples) on a multi-gram scale (50.0 mmol) by the reaction of sugar and acetic anhydride under microwave irradiation in the absence of a volatile organic solvent. The desired product was easily obtained by simple extraction with toluene from the reaction mixture, and I2/ILs can be readily recovered and reused at least six times without obvious loss in the yield. When the scale of the per-O-acetylation reaction was increased to 50.0 mmol, the desired product was still obtained in 90% yield after five recycles.
