Synthesis and characterization of new galactosylated-based N2O-donors tridentate ligands

The synthesis and characterization of three novel N2O-donor ligands containing the group 4-[1-β-d-2,3,4,6-tetra-O-acetyl-galactosyl)]benzaldehyde are presented. The insertion of this group was designed to increase the absorption of the prodrug in tumor cells, and is part of an ongoing work in our group with tridentate ligands to develop potential cobalt(III) prodrugs. The synthetic route described here allowed the isolation of pure ligands with yields ranged 81–89%. Finally, compounds were characterized by IR, NMR and HRMS (ESI+).

COMPOSITION FOR DESTRUCTION OF MICROALGAE OR SPHAEROCARPUS

The present disclosure relates to a composition for the destruction of microalgae or mosses. The composition for the destruction of microalgae or mosses may suppress the growth and proliferation of microalgae when treated in moss cultivation facilities, marine microalgae cultivation facilities, areas in which green or red tide is occurring, or areas in which green or red tide is expected to occur, thereby preventing damage caused by the green or red tide.

Encapsulation of the BeII cation: Spectroscopic and computational study

The structures of a series of tetracoordinate beryllium(II) complexes with ligands derived from tertiary-substituted amines have been computationally modeled and their 9Be magnetic shielding values determined using the gauge-including atomic orbital (GIAO) method at the 6-311++g(2d,p) level. A good correlation was observed between calculated 9Be NMR chemical shifts when compared to experimental values in polar protic solvents, less so for the values recorded in polar aprotic solvents. A number of alternative complex structures were modeled, resulting in an improvement in experimental versus computational 9Be NMR chemical shifts, suggesting that in some cases full encapsulation on the beryllium atom was not occurring. Several of the synthesized complexes gave rise to unexpected fluorescence, and inspection of the calculated molecular orbital diagrams associated with the electronic transitions suggested that the rigidity imparted by the locking of certain conformations upon BeII coordination allowed delocalization across adjacent aligned aromatic rings bridged by BeII.

Synthesis, structure, spectra and redox chemistry of iron(III) complexes of tridentate pyridyl and benzimidazolyl ligands

A series of high-spin octahedral 1:2 iron(III) complexes of Schiff bases derived from salicylaldehyde and aromatic amines and the 1:1 and 1:2 complexes of bis(pyridin-2-yl)-aza and bis(benzimidazol-2-yl)-aza and -thioether ligands have been isolated. The

Synthesis and Crystal Structures of a Series of Amide Copper(II) Complexes

The synthesis and structural determination by X-ray crystallography of four amide copper(II) complexes has been performed: NH(CH2)nPh>(solv)>2 (X = H, solv = H2O, n = 2 1 or 1 2; X = OH, solv = H2O, n = 2 3; solv = MeCN, n = 1 4).In all complexes the co-ordination around the copper atom is a more or less distorted square-based pyramid where the three ligands of the square are unchanged: one oxygen atom of the amide group and two nitrogen atoms of the pyridine nucleus and of the tertiary amine.The fourth ligand is a water molecule (1-3) or an acetonitrile solvent molecule (4).The axial ligand is the oxygen atom of the phenolic group in complexes 3 and 4, while in 1 and 2 this site is occupied by an oxygen atom of a triflate counter ion.
