Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In homogeneous catalysis, catalysts are in the same phase as the reactants.499-40-1, C12H22O11. A document type is Article, introducing its new discovery., Related Products of 499-40-1

The dinucleating ligand, tpbpd (tetrapyridyl biphenylenediamine) forms a dicopper complex with practically no electronic coupling between the two copper (II) centres. The EPR spectrum of the complex is consistent with coordination of each copper ion to two nitrogens of the binuclear ligand. Cyclic voltammogram of the complex also reveals that the two copper (II) centres have identical ligating environment. This dimeric copper (II) complex is found to be a very efficient catalyst for the cleavage of plasmid DNA in the absence of any added cofactor. The amount of conversion of supercoiled form (Form I) of plasmid to the open circular form (Form II) depends on the concentration of the complex as well as the duration of incubation of the complex with DNA. The maximum rate of conversion of the supercoiled form to the nicked circular form at pH 7.5 in the presence of 150 muM of the complex is found to be 1.8 × 10-3 s-1.

Six new nickel(II) complexes have been synthesized by the reaction of the nitrogen donor coligand 2,2?-dipyridylamine (dipyam) and three different alpha-hydroxyacids (H2L?) with different levels of bulkiness, namely lactic, 2-methyllactic and mandelic acids. Two types of compounds have been obtained: neutral complexes of formula [Ni(HL?)2(dipyam)] and the cationic metal complexes of general formula [Ni(HL?)(dipyam)2](HL?). The structures of the cationic metal complexes have been elucidated by single-crystal X-ray diffraction. The role of the second coordination sphere in the metallosupramolecular organization through different hydrogen-bonding patterns has been analysed. The thermal behaviour of all new compounds has been investigated.

Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 3301-94-8, Name is 6-Butyltetrahydro-2H-pyran-2-one.

Two thermodynamic parameters – entropy (deltaS) and enthalpy (deltaH) – ideally describe the thermodynamics of how the retention of an analyte in a stationary phase depends on the temperature. The paper examines the conversion of an analyte’s entropy and enthalpy into chromatographically more meaningful equivalents: its characteristic temperature and thermal constant. Thermodynamic and characteristic parameters of 29 enantiomer pairs of chiral analytes, analysed with four cyclodextrin stationary phases, were measured, tabulated, and investigated. The distribution of all newly-measured characteristic parameters was found to be similar to the known distribution of these parameters for some 12,000 pairs of analytes, analysed with several stationary phases. This similarity suggests that the peak widths of the investigated analytes in temperature-programmed analyses should be generally the same as the peak widths of other similarly retained analytes. It also suggests that the previously-known optimum general heating rate (about 10 oC/tM, i.e. 10C per hold-up time) is also the general optimum for temperature-programmed enantioselective GC analyses with cyclodextrins as stationary phases.The optimum general heating rate corresponds to the shortest analysis time for a predetermined peak capacity. It can substantially differ from specific optima corresponding to the best separation of particular peak pairs. Theoretical prediction of these specific optima requires more complex non-ideal thermodynamic models, and more accurate measurement of the parameters involved-these topics that are outside the scope of this report.

The synthesis is described of four pentasaccharides, which are structurally related to the bacterial capsular polysaccharide isolated from E. coli K5 (010/K5/H40), i.e. the so-called K5 antigen.These four synthetic compounds comprise: (i) a pentasaccharide that is structurally identical to the K5 antigen (i.e. compound 16); (ii, iii) two pentasaccharides containing two and three O-sulphated groups respectively on defined positions (i.e. compounds 15a and 15b); (iv) a pentasaccharide that is O-sulphated on all hydroxyl groups (i.e. compound 17).These four K5-antigen-related pentasaccharides were synthesized from the fully protected pentasaccharides 13a and 13b.The preparation of compounds 13a,b was based on coupling of disaccharide 6a with the disaccharide 10a or 10b to give tetrasaccharides 11a,c, respectively, which in turn were coupled to monosaccharide 12.Deblocking of the pentasaccharides 13a,b and conversion into the pentasaccharides 15a and 15b was performed by saponification of the ester functions, O-sulphation, hydrogenalysis and finally selective N-acetylation. compound 16 was obtained from 13a,b by saponification of the ester functions, deblocking of the benzyl and N-protective groups, followed by selective N-acetylation.The persulphated derivative 17 was obtained from 15a by extensive O-sulphation.The structure of the K5-antigen-related pentamers was confirmed by 1H NMR- and 13C NMR-spectroscopical techniques.

(Poly)phenols are a large group of dietary compounds present in fruits and vegetables; their consumption is associated with health beneficial effects. After ingestion, (poly)phenols suffer extensive metabolization, and the identification of their metabolites is an emerging area, because these metabolites are considered the effective bioactive molecules in the human organism. However, a lack of commercially available standards has hampered the study of metabolite bioactivity and the exact structural confirmation in biological samples. New (poly)phenol metabolites previously identified in human samples after the intake of berry juice were chemically synthesized. Efficient chemical reactions were performed with moderate to excellent yields and selectivities. These new compounds could be used as standard chemicals for confirmation of the structure of metabolites in biological samples and will also allow mechanistic studies in cellular models.
