A novel dinuclear copper(II) complex 2 bearing double μ 2 -oxo bridges has been obtained by in situ Cu II ion catalysis and complexation with the H 2 O 2 oxidant of C.I. Disperse Yellow 79 (1), where a new dianionic ligand is in situ formed having an additional phenolic group and it coordinates with the central Cu II ion as a tridentate chelating ligand. Furthermore,...
Four heterocyclic Disperse Red azo dyes having the same benzothiazole/azo/benzene skeleton, namely three classical C.I. Disperse Red 145, 152 and 153 (1–3) and another C.I. Disperse Red 153 substitute (4), have been structurally characterized and compared in this paper. X-ray single-crystal diffraction analyses reveal that they have similar planar molecular conformation between azo and aromatic units...
