Synthesis and biological studies of complexes of 2- amino-N(2-aminobenzoyl) benzohydrazide with Co(II), Ni(II), and Cu(II)

The present work is concerned with the synthesis and coordination compounds of 2-amino-N(2-aminobezoyl) benzohydrazide (ABH). The ligand was synthesized by the reaction of methylanthranilate and hydrazine in 2:1 molar ratio. It can be viewed as a modified

Stabilizing and Activating Nitrogen Catenates

The remarkably stable catenated hexa-nitrogen chain in bis(benzotriazene-4-one) is structurally, theoretically, and spectroscopically characterized to illustrate the durability of the central N-N bond in this hexaazo chain. The reactions of this species illustrate the potential of these nitrogen catenates for the preparation of other condensed heterocycles, such as bispyrazolones, by thermal nitrogen exclusion or by trapping the single ring-opened Dimroth intermediates. In these latter reactions, 2-naphtholate anion condenses with bis(benzotriazene-4-one) to trap and retain a zwitterionic diazonium intermediate as an isolated diazo product, whereas transition metals ring effect ring-extrusion of dinitrogen from the Dimroth intermediate to generate chelating σ-aryls. The catenated nitrogen species can be stabilized by incorporating strong formal sp2-sp2 N-N σ bonds with orthogonal orientations. Extending these stabilization and activation principles may allow these types of nitrogen catenates to be useful synthons for other polyaza species. Strengthening the chains: The remarkably stable catenated hexa-nitrogen chain in bis(benzotriazene-4-one) is structurally, theoretically, and spectroscopically characterized. The catenated nitrogen species can be stabilized by incorporating strong formal sp2-sp2 N-N σ bonds with orthogonal orientations. Extending these principles may allow such nitrogen catenates to be useful synthons for other polyaza species.

Synthesis of pyridine-based 1,3,4-oxadiazole derivative as fluorescence turn-on sensor for high selectivity of Ag+

An oxadiazole derivative(OXD) containing symmetrical pyridine-2- formamidophenyl-binded moiety was synthesised as fluorescence turn-on sensor OA1. Its ultraviolet-visible(UV-vis) and fluorescent spectra(FS) gave prominent fluorescence enhancement only for monovalent silver ion(Ag+) in HEPES buffer solution (10 mM, pH = 7.0, DMF-H2O, 9:1, v/v), which indicated the photo-induced electron transfer(PET) occurred from the donor of pyridine-2-formamidophenyl group to oxadiazole fluorophore. The present study demonstrated that OA1 was a viable candidate as fluorescent receptor for a new Ag+ sensor. And the results of fluorescent spectral titration showed this sensor formed 1:1 complex with Ag+.

Effect on the inhibitory activity of potential microbes on the complexation of methyl anthranilate derived hydrazide with Cu, Ni and Zn (II) metal ions

The hydrazide ligand 2-amino-(N-aminobezoyl)benzohydrazide [ABH] have been synthesized and characterized by 1H-NMR, 13C-NMR, ES +-MS, elemental analyses and infrared studies. The ligand was complexed with Ni(II), Cu(II) an

Tetraacyl hydrazines and 3,3′-biquinazoline-4,4′-diones; synthesis, studies of rotational barriers and deracemisation

The barrier to rotation around the N-N bond in 3,3′-biquinazoline-4,4′-dione is estimated to be 96 kJ mol-1, significantly higher than in acyclic tetraacyl hydrazines (84 kJ mol-1). Both dynamic chiroptical and NMR studies of 3,3′-bi

Oxidative cyclocondensation of thio(seleno)-amides and ureas 1. 2-thioxo-4-quinazolone

It has been found for the first time that 2-thioxo-4-quinazolone in the presence of acid catalysts in dimethyl sulfoxide is converted to 8H,15H-1,2,4-thiadiazolo[3, 2-b:5, 4-b′]diquinazoline-8, 15-dione. The reaction proceeds via oxidative cyclocondensation. The formation of this structure in preference to five other proposed isomers is substantiated using quantum-chemical methods. 1997 Plenum Publishing Corporation.
