A new family of copper(I) complexes with "glycoligands" containing a central saccharide scaffold, with 2-picolyl ether groups or 2-picolylamine or N-imidazolylamine groups, has been prepared and characterized. For this purpose, the following tetradentate ligands have been synthesized: methyl 2,3-di-O-(2-picolyl)-alpha-D-lyxofuranoside (L1), 1,5-anhydro-2-deoxy-3,4-di-O-(2-picolyl)-d-galactitol ...

The article considers a sorption method for extracting copper ions from model nitric acid solution based on of electrolytic refining silver with using sorbents bis-picolylamine functional groups: Dowex M-4195 and AXIONIT BPA. possibility to residual concentrations in the less than 10 mg/l is shown. working capacity both samples under batch conditions, as well dynamic exchange full ?onditions (c...

Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) is used for the multiplex detection and characterization of diverse analytes over a wide mass range directly from tissues. However, analyte coverage with MALDI MSI is typically limited to the more abundant compounds, which have m/z values that are distinct from MALDI matrix-related ions. On-tissue analyte deriva...

Three mononuclear 2-picolylamine-containing zinc(III) complexes viz [(2-PA)2ZnCl]2(ZnCl4)] (Zn1), [(2-PA)2Zn(H2O)](NO3)2] (Zn2) and [Zn(2-PA)2(OH)]NO3] (Zn3) were synthesized fully characterized. Spectral X-ray structural characteristics showed that the Zn1 complex has a square-pyramidal coordination environment around zinc(II) core. The hydroxide Zn3 was non-covalently functionalized with few ...

This chapter reviews contemporary approaches to the morphological influences on stress in certain Pama-Nyungan languages, including Diyari, Dyirbal, and Warlpiri. To account for the variation found in these languages, nine different theories are developed that differ in the constraints responsible for edge effects in stress and the alignment of morphological and prosodic structure. The factoria...

Here we report on inroads concerning increased substrate breadth via the picolylamine organocatalyst template, a vicinal chiral diamine based on a pyridine-primary amine motif. The addition of cyclohexanone to β-nitrostyrene has many catalyst solutions, but cyclopentanone and isobutyraldehyde additions continue to be challenging. PicAm-3 (10 mol%) readily allows the Michael addition of cyclopen...
