Comparative photohalogenation of phenylglucopyranoside and its oxidation derivatives

The photobrominations of the peracetylated phenyl thio-1-beta-D-glucopyranoside and of the corresponding sulphoxides and sulphone have been investigated. The differences observed in both substrate reactivity and substitution regioselectivity indicate an easier homolysis of the anomeric C-H bond in the thioglycoside.

Photophysical and electrochemical properties of new ortho-metalated complexes of rhodium(III) containing 2,2?-dipyridylketone and 2,2?-dipyridylamine. An experimental and theoretical study

Two new ortho-metalated rhodium(iii) complexes of the formula [Rh(ppy) 2(L)]+, ppy = 2-phenylpyridine and L = 2,2?-dipyridylketone (dpk) (1), 2,2?-dipyridylamine (HDPA) (2) have been synthesized and subjected to X-ray diffraction crystal structural, photophysical and electrochemical studies. Density functional theory calculations have also been performed to get rationalizations of the optical orbitals and redox orbitals concerning photophysical and electrochemical data. Complex 1 exhibits the triplet ligand-to-ligand charge transfer ( 3LLCT) [pi(ppy)-pi*(dpk)] phosphorescence at 77K (520 nm) and at room temperature (555 nm), while complex 2 shows triplet ligand centred (3LC) [pi-pi*(ppy)] phosphorescence only at 77K (460 nm). Both complexes 1 and 2 have similar irreversible oxidation potentials (+1.19 V for 1 and +1.15 V for 2 vs. Fc/Fc+). These two complexes show different characteristics in the reduction process: a reversible process occurs for 1 at -1.31 V, while an irreversible process is observed for 2 at -1.85 V.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.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. In a Article，once mentioned of 499-40-1, name: (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

Blue luminescent organoaluminum compounds: Al(CH3)2(dpa), Al2(CH3)5(dpa)2, Al4(O)2(CH3)6(dpa)2, and Al(pfap)3, dpa = Deprotonated Di-2-pyridylamine, pfap = Deprotonated 2-pentafluoroanilinopyridine

The reactions of Al(CH3)3 with di-2-pyridylamine (dpaH) yielded a mononuclear zwitterion complex, Al(CH3)2(dpa) (1), a dinuclear complex, Al2(CH3)5(dpa) (2), and a tetranuclear complex, Al4(O)2(CH3)6(dpa)2 (3), depending on the stoichiometry and conditions of the reactions. The crystal structures of all three compounds were determined by single-crystal X-ray diffraction analyses. All three compounds emit an intense blue color in solution and the solid state at lambdamax = 475, 445, and 450 nm, respectively, when irradiated by an UV light. Molecular orbital calculations using ab initio methods (Gaussian 94) on dpa, dpaH, and compound 1 were performed which revealed that the aluminum ion in compounds 1-3 plays a key role in stabilizing the complexes and promoting the blue luminescence. The reaction of Al(CH3)3 with 2-pentafluoroanilinopyridine (pfapH) resulted in the formation of a mononuclear octahedral complex, Al(pfap)3 (4). Variable-temperature and COSY 1H NMR established that compound 4 is highly fluxional in solution due to a rapid interconversion of mer and fac isomers, with the mer isomer dominating at low temperature. The structure of the fac isomer of 4 was determined by X-ray diffraction. Compound 4 emits at lambdamax = 409 nm when irradiated by an UV light.

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.name: (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, you can also check out more blogs about499-40-1

Monomeric, N-functionalised amido complexes of aluminium: Synthesis of [AlCl{NR(8-C9H6N)}2] (R = H or SiMe3) and [Al{N(2-C5H4N)-(2-C5H4N)} 3]

Routes have been devised to a series of aluminium(III) amide complexes containing either of the bulky, N-functionalised amides NR(8-C9H6N)- (R = H or SiMe3) or N(2-C5H4N)2-. Reaction of the lithium amides [{Li(OEt2)[NR(8-C9H6N)]}2] (R = H or SiMe3) with AlCl3 afforded [AlCl(NR(8-C9H6N)]2] (R = H or SiMe3) respectively. The crystal structure of five-co-ordinate [AlCl(NH(8-C9H6N)}2] shows it to be monomeric in the solid state with intramolecular dative interactions between the aluminium centre and both aromatic nitrogen atoms. Treatment of NH(2-C5H4N)2 with [AlH3(NMe3)] yielded the six-co-ordinate complex [Al{N(2-C5H4N)(2-C5H4N)} 3], the crystal structure of which confirms it to be monomeric with intramolecular Al-N (aromatic) dative bonds from one pyridyl functionality of each amide ligand. In solution this complex exhibits fluxional behaviour which has been investigated by variable-temperature 1H NMR spectroscopy.

Synthesis of novel papulacandin d analogs and evaluation of their antifungal potential

Systemic fungal infections are a growing problem in contemporary medicine and few drugs are licensed for therapy of invasive fungal infections. Differences between fungi and humans, like the presence of a cell wall in fungal cells, can be explored for designing new drugs. (1,3)-beta-D-glucan synthase, an enzyme that catalyzes the synthesis of (1,3)-beta-D-glucan, a structural and essential component of the fungal cell wall, is absent in mammals and this makes it an excellent target for the development of new antifungal agents. Papulacandins are a family of natural antifungal agents targeting (1,3)-beta-D-glucan synthase. In this study we describe the synthesis and biological evaluation of two new Papulacandin analogs as potential (1,3)-beta-D-glucan synthase inhibitors.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 10343-06-3, help many people in the next few years., Reference of 10343-06-3

Structures, magnetic properties, and EPR studies of tetranuclear copper(II) complexes [Cu4(OH)4L4]4+ (L = bpa, bipy) stabilized by anions containing decahydro-closo-decaborate anion

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. The magnetic properties of three compounds under study are different; the magnetic moment has been found to increase, to decrease and remain unchanged when increasing temperature.

Subtlety of the spin-crossover phenomenon observed with dipyridylamino-substituted triazine ligands

Reactions of the new, closely related ligands 4,6-dichloro- N,N-di(pyridine-2-yl)-1,3,5-triazine-amine (Cldpat) and 6- chloro-N’-phenyl-N,N- di(pyridin-2-yl)-1,3,5-triazine-2,4-diamine (Cladpat) with iron(II) thiocyanate produced coordination compounds with drastically distinct magnetic properties. The compound trans-[Fe(Cldpat)2(NCS)2](H2O) (1) is a highspin complex from room temperature down to 5 K whereas the analogous compound trans-[Fe(Cladpat) 2 (NCS) 2] (2) exhibits spin-crossover (SCO) properties with T1/2 = 178K. Compounds 1 and 2 (both in its low-spin and high-spin states) have been structurally characterized by X-ray diffraction studies, which revealed identical metal coordination spheres. The SCO properties of 2 have been thoroughly investigated by temperature-dependent magnetic susceptibility measurements and differential scanning calorimetry (DSC), and a LIESST process with rapid relaxation of the trapped HS species has been observed. The equivalent coordination compound with selenocyanate anions, namely [Fe(Cladpat) 2 (NCSe) 2] (3) also displays SCO properties, although more gradual and with a lower T 1/2 value of 166 K.
