The iron(II) spin crossover dinuclear compound [Fe(dpa)(NCS)2] 2bpym where dpa = 2,2?-dipyridylamine and bpym = 2,2?-bipyrimidine has been synthesized and characterized. Variable-temperature magnetic susceptibility and 57Fe Moessbauer spectroscopy data provide evidence for a rather complete and continuous S=2 (HS)?S=0 (LS) spin-crossover behavior taking place in the temperature range 400-50 K (T1/2=245 K) without the presence of a plateau at 50% of conversion. The absence of such plateau, which is characteristic of all dinuclear compounds so far studied, is interpreted in terms of synergetic effect between intramolecular and intermolecular interactions.

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.Recommanded Product: 499-40-1, you can also check out more blogs about499-40-1

The syntheses of 44 1-carbamates from six different 1-O-unprotected carbohydrate derivatives (compounds 1-6), representing typical protecting pattern in glycoside synthesis, are described. The carbamate function is N-unsubstituted (compounds 1b-6b), mono- (compounds a: N-trichloroacetyl, c: N-monochloroacetyl, d: N-acetyl, e: N-ethyl, f: N-allyl, g: N-phenyl) or disubstituted (compounds h: imidazolyl, i: N-diethyl, j: N-diphenyl). Additionally, three N-chlorosulfonyl carbamates are synthesized and used as intermediates for the synthesis of N-unsubstituted compounds b. The accessibility of these compounds is described and compared. Some of the carbamates (1, 4, 5a-j) are used as model compounds for systematic investigations in glycoside syntheses. Selected experimental data (reaction conditions, anomeric ratios, rotation values, selected NMR data) are tabulated.

Tetranuclear copper(II) cationic complex [Cu4(bpa)4(OH)4]4+ stabilized by chained polymeric silver(I) anionic complex {Ag[B10H10]}nn? and two DMF molecules with the general formula {[Cu4(bpa)4(OH)4(DMF)2][Ag[B10H10]]4·10 DMF}n has been synthesized. The target complex has been prepared in one step when [Ag2[B10H10]] was allowed to react with CuCl in the presence of bpa in DMF; the reaction has been performed in air. Copper(I) has been oxidized in air in the presence of bpa to form the tetranuclear cationic complex. The target compound has been studied by IR spectroscopy as well as powder and single crystal X-ray diffractions. The electronic structure and magnetic properties of the complex have been studied by EPR spectroscopy and magnetic susceptibility methods and the obtained data have been compared with those obtained for related tetranuclear bipy-contained copper(II) complexes [Cu4(bipy)4(OH)4][Cu2[B10H10]3]·4CH3CN and {[Cu4(bipy)4(OH)4][B10H10]2(DMSO)2} with the known structures.

Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme. Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. 10034-20-5, C14H22ClNO9.

An efficient strategy to construct beta-O-2-amino-2-deoxyglycopyranosidic linkages using glycosyl sulfoxides is demonstrated. Phenylsulfenyl 2-deoxy- 2-trifluoroacetamido glycopyranosides were found to be reactive glycosyl donors in both solid- and solution-phase glycosylations, affording the corresponding beta-glycosides exclusively and in high yield. The trifluoroacetamido group was removed under mild conditions, allowing orthogonal derivatization of multiple protected amino groups on an oligosaccharide or glycoconjugate. On the basis of the results with these glycosyl donors, a solid-phase beta-linked disaccharide library was constructed. The scope and flexibility of this approach will be discussed.

Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11.

Two new compounds, [Cu(acac)(N3)(dpyam)] (1), (acac = acetylacetonate; dpyam = di-2-pyridylamine) and [Cu(mu-N3-kappaN1)(C2N3- kappaN1) (dpyam)]2 (2), have been synthesized and characterized by single-crystal X-ray diffraction and magnetic analyses. Compound 1 is a mononuclear compound in which each of two independent Cu(II) ions is penta-coordinated with a distorted square pyramidal geometry with distortion parameters tau = 0.21 and 0.16. In contrast, compound 2 is an azido-bridged dinuclear compound with monodentate dicyanamide anions and the Cu(II) ions display a distorted trigonal bipyramidal geometry with tau = 0.73 and end-on azido bridges providing an equatorial-axial position between the metal ions. The EPR spectra of powdered samples for 1 and 2 have also been investigated. Magnetic susceptibility measurements of compound 2 reveal a very weak ferromagnetic interaction between the Cu(II) ions with a J value of +5.8 cm-1.

A spectrophotometric and (1)H NMR kinetic study of the reactions of cis-[PtPh2(CO)(SEt2)] with an extended series of dinitrogen chelating ligands (N-N) of widely different steric and electronic properties has been carried out in dichloromethane solution. The contemporary presence in thestarting substrate of a labile (SEt2) and a relatively inert (CO) ligand in trans to firmly bonded phenyl groups makes it possible to distinguish three different reactivity patterns, according to the nature of the bidentate ligands used. Relatively stable open-ring species of the type cis-[PtPh2(CO)(N-N)] were isolated with the long chain ligand 1,4-diaminobutane and with N-phenyl-1,2-diaminoethane in which one of the two nitrogens exhibits very low basicity and considerable encumbrance. For the other dinitrogen ligands, the relative magnitude of the rates of attack atthe metal and of ring closure dictates whether the chelate formation isseen as a simple conversion of the starting complex into the final chelate [PtPh2(N-N)] or as a two stage process with evidence for the formation of an open-ring species. With rigid or highly sterically hindered ligands such as 2,2′-dipyridyl, 1,10-phenantroline, dicyclohexylethylenediimine or N,N,N’,N’-tetramethylethylenediamine a single stage process fromthe starting complex to the final chelate compound was observed. The rate determinig step is thought to involve slow dissociation of SEt2 from the complex followed by fast ring closing. With 1,2-diaminoethane, 1,3-diaminopropane, 2-aminomethylpyridine, 2-aminoethylpyridine, 2,2′-dipyridylamine and 2,2′-dipyridylsulfide a slow ring closure of the open-ring complex follows the fast entry of the first end of the ligand. The substrate shows a remarkable selectivity between the two nucleophilic ends of an unsymmetrical bidentate ligand with a clear preference for the most basic and the less hindered end. Open-ring reaction intermediates cis-[PtPh2(CO)(N-N)] were characterised in solution by their IR, (1)H and (13)CNMR spectra and their spectroscopic characteristic are compared to those of the parent amine and phosphine compounds. The final chelate compounds [PtPh2(N-N)] were either isolated as solids or characterised in solution.

The linear trirhodium compound, Rh3(dpa)4Cl 2 (1), and its one-electron oxidation product, [Rh 3(dpa)4Cl2]BF4 (2), have been synthesized and studied extensively. The magnetic measurement for compound 1 shows that it possesses one unpaired electron that is assigned to occupy the sigmanb orbital (2A2) by DFT calculations. Upon oxidation, a beta-spin electron of 1 is removed, that causes compound 2 to exhibit a triplet ground state. DFT calculations indicate that the two unpaired electrons of 2 occupy sigmanb and delta* orbitals (3B1), which is supported by 1H NMR spectrum. Unlike their isoelectronic analogues [Co3(dpa)4Cl 2] (3) and [Co3(dpa)4(Cl)2]BF 4 (4), both compound 1 and 2 do not display the spin-crossover phenomenon. The reason may be attributed to the relative large energy gap between 3B1 and open-shell singlet 1B 1 states.
