Poly(cyclic) oxamates represent novel and potentially multidentate ligands for coordination chemistry. To obtain them, the treatment of 2-nitroaniline with two equivalents of oxalyl chloride afforded N,N'-bis(2-nitrophenyl)oxalamide (1), and by reduction

We need a practical, inexpensive, and green way to reduce the environmental pollutants, especially for dye wastewater. The discharge of industrial wastewater such as organic dyes will cause serious pollution to water bodies, thereby affecting people's liv

The preparation, characterization, and evaluation of a cobalt(III) complex (Figure presented.) with 13-membered tetraamide macrocyclic ligand (TAML) is described. This is a square-planar (X-ray) S?=?1 paramagnetic (1H NMR) compound, which becomes an S?=?0 diamagnetic octahedral species in excess d5-pyridine. Its one-electron oxidation at an electrode is fully reversible with the lowest E? value (0.66?V vs SCE) among all investigated CoIII TAML complexes. The oxidation results in a neutral blue species which is consistent with a CoIII/radical-cation ligand. The ease of oxidation is likely due to the two benzene rings incorporated in the ligand structure (whereas there is just one in many other CoIII TAMLs). The oxidized neutral species are unexpectedly EPR silent, presumably due to the π-stacking aggregation. However, they display eight-line hyperfine patterns in the presence of excess of 4-tert-butylpyridine or 4-tert-butyl isonitrile. The EPR spectra are more consistent with the CoIII/radical-cation ligand formulation rather than with a CoIV complex. Attempts to synthesize a similar vanadium complex under the same conditions as for cobalt using [VVO(OCHMe2)3] were not successful. TAML-free decavanadate was isolated instead.
Metal Template Reactions. XVI. Design and Synthesis of Primary Diamine Ligands with Additional Nitrogen Donor Atoms
Black, David St. C.,Rothnie, Neil E.
, p. 1141 - 1147 (2007/10/02)
Five new primary diamines (8), (10), (12), (20) and (22) have been synthesized.These compounds contain additional nitrogen donor atoms suitable for metal chelation.An improved preparation of the triamine (6) is also reported.
