Coordination chemistry of palladium(II) and platinum(II) complexes with bioactive Schiff bases: Synthetic, spectral, and biocidal aspects was written by Sharma, K.;Biyala, M. K.;Swami, M.;Fahmi, N.;Singh, R. V.. And the article was included in Russian Journal of Coordination Chemistry in 2009.Application In Synthesis of 7-Nitroindoline-2,3-dione This article mentions the following:
The Schiff bases, 5-nitro-indol-2,3-dionehydrazinecarboxamide (HSCZ1) and 7-nitro-indol-2,3-dionehydrazinecarboxamide (HSCZ2), were synthesized by the condensation of 5-nitro-indol-2,3-dione and 7-nitro-1H-indol-2,3-dione with semicarbazide hydrochloride, resp. The palladium(II) and platinum(II) complexes were prepared by mixing palladium chloride and platinum chloride in 1:2 molar ratios with monobasic bidentate Schiff bases. The ligands and complexes of palladium and platinum were characterized by elemental analyses, m.p. determinations, conductance measurements, mol. weight determinations, and IR, 1H NMR, and UV spectral studies. The ligands coordinate to the metal atoms in a monobasic bidentate mode, coordinating through oxygen and nitrogen donor systems. Thus, a tetracoordinated environment around the metal atom is proposed. Both the ligands and their complexes were screened for their biol. activity on several pathogenic fungi and bacteria and possess appreciable fungicidal and bactericidal properties. Plant growth regulating activity of one of the ligands and its complexes also was recorded on gram plant, and results are discussed. In the experiment, the researchers used many compounds, for example, 7-Nitroindoline-2,3-dione (cas: 112656-95-8Application In Synthesis of 7-Nitroindoline-2,3-dione).
7-Nitroindoline-2,3-dione (cas: 112656-95-8) belongs to indole derivatives. Indole produced by Proteus, Pseudomonas, Escherichia and other species was shown to be a growth promoting factor in Arabidopsis thaliana.Indole was synthesized in moderate yield via an o-naphthoquinone catalyzed tandem cross-coupling of substituted aniline and benzylamine under aerobic oxidation conditions.Application In Synthesis of 7-Nitroindoline-2,3-dione
