The tris complex of Ru(II) with 2,2′-dipyridylamine (HDPA) has been prepared and characterized.Luminescence spectra, lifetimes, and photoselection spectra have been measured for various protonated and deprotonated forms of the complex in aqueous and nonaqueous solution.The fully protonated 2+ shows a weak, broad, symmetric, and structureless emission of microsecond lifetimes at low energy assigned as a dd+ phosphorescence.The complexes of the deprotonated dipyridylamine ligand (DPA-) exhibit broad, asymmetric, and structureless emission at higher energy with microsecond lifetimes.The emission for these deprotonated complexes is assigned as charge-transfer IId* emission, and, as a consequence, the emission for the – and – complexes (previously reported as dII* emitters) is reconsidered.The + and – complex ions show spatially isolated (single-ring) emission in nonaqueous solvents; however, evidence exists that the emission for the neutral 0 complex is multiring in nature.Spectral data are also presented for an aquated form of the fully deprotonated complex, -, which has also been isolated as a solid product.

The preparation, characterization and crystal structures of the mono(dpyam) copper(II)nitrato complexes [Cu(dpyam)(O2NO)2] (1) and [Cu(dpyam)(O2NO)2]·2H2O (2) (dpyam = di-2-pyridylamine) have been investigated. Compound 1 consists of two crystallographically independent [Cu(dpyam)(O2NO)2] neutral molecules. These molecules are linked into infinite chains by the bridging bidentate nitrate groups in the long-bonded tetragonal positions giving an elongated rhombic octahedral stereochemistry. The structure of 2 is composed of a couple of crystallographically independent [Cu(dpyam)(O2NO)2] neutral molecules and four water molecules in the lattice. Each copper atom exhibits a tetrahedrally distorted square base of the N2O2 plane, with the second oxygen atoms of the monodentate nitrato groups weakly bound in nearly axial positions giving an extremely distorted octahedral coordination geometry.

Synthetic Route of 14215-68-0. 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. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide. In a document type is Article, introducing its new discovery.

A new direct method for beta-selective glycosylation with an N-acetylglucosamine (GlcNAc) donor was developed. This substrate, which can be readily prepared from commercially available GlcNAc in two steps, contains a 4-O-tert-butyldimethylsilyl (TBDMS) protecting group as a key component. We found that this functionality could have a favorable effect on the reactivity of the GlcNAc donor. Glycosylation with the armed donor using primary alcohols in the presence of a catalytic amount of trimethylsilyl trifluoromethanesulfonate (TMSOTf) in 1,2-dichloroethane smoothly gave the desired coupling products in good yields with complete beta-selectivity, while sterically hindered acceptors were less efficient.

Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. Introducing a new discovery about 85064-61-5, Name is Tetrahydropyranyl-4-acetic acid, 85064-61-5.

The tetrahydropyran 4-(((3-(2,2-dimethyltetrahydro-2H-pyran-4-yl)-4-phenylbutyl)amino)methyl)-N,N-dimethylaniline was reported to disrupt the SCFSKP2 E3 ligase complex. Efficient syntheses of this tetrahydropyran derivative and analogues, including the des-dimethyl derivative 4-(((3-(tetrahydro-2H-pyran-4-yl)-4-phenylbutyl)amino)methyl)-N,N-dimethylaniline, are described. The enantiomers of the des-dimethyl compound were obtained using Evans’ chiral auxiliaries. Structure-activity relationships for these tetrahydropyrans and analogues have been determined by measurement of growth-inhibitory activities in HeLa cells, which indicated a non-specific mechanism of action that correlates with inhibitor lipophilicity. However, preliminary data with (R)-and (S)-4-(((3-(tetrahydro-2H-pyran-4-yl)-4-phenylbutyl)amino)methyl)-N,N-dimethylaniline showed enantioselective inhibition of the degradation of p27 in a cell-based assay that acts as a reporter of SKP2 activity.

A series of homo and heterocyclic alkanoates were prepared and evaluated as insect attractants toward Blattella germanica (L.) and Supella longipalpa (F.).Among these compounds, the tetrahydrofurfuryl alkanoates and 4-tetrahydropyranyl hexanoate showed relatively better activity.It was also observed that, in general, the five-membered compounds were better performers than their six-membered counterparts.The introdiction of an oxygen atom in the ring enhanced the activity, irrespective of the ring size.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum. Synthetic Route of 499-40-1, Synthetic Route of 499-40-1, C12H22O11. A document type is Article, introducing its new discovery.

The synthetic details, characterization data and single crystal X-ray structural analyses of [Zn(dpa)(N3)2] (1) and [Zn(dpa)(N3)(NO3)]2 (2) (dpa=2,2?- dipyridylamine) are described. Structural study reveals that the zinc(II) centre in 1 is in a pseudotetrahedral ZnN4 environment ligated by two terminal azide N atoms and two pyridine N atoms of the chelator. The coordination polyhedron around each metal ion in dinuclear 2 is best described as a ZnN4O2 distorted octahedron linked by two end-on azido bridges. The mononuclear units in 1 are engaged in bifurcated intermolecular hydrogen bonding (N-H…N) between amine N of dpa and coordinated N of azide along with aromatic pi-pi stacking leading to a 2D sheet. In 2, the dinuclear units participate in intermolecular N-H…O hydrogen bonding between amine N of dpa and bound O of bidentate nitrate in combination with pi-pi interactions resulting to a 3D supramolecular continuum. 1 and 2 display high energy intraligand 1(pi-pi*) fluorescence and intraligand 3(pi-pi*) phosphorescence in glassy solutions (DMF at 77 K). A band (372 nm) observed for both 1 and 2 in their solid-state emission spectra is an excimeric emission arising due to aromatic pi-pi interaction. The role of dpa, a tailored diimine (-N=C-NH-C=N-) in 1 and 2 is discussed towards functionalisation on crystal engineering and luminescence behaviour.
