“…[9] Demand dyes should have brilliance, a wide spectrum of colours, and outstanding fastness qualities, in addition to their environmental and economic advantages. [10][11][12][13] Textile printing is the process of adding colour to quantities of fabrics to generate artistic designs, Dyes or pigments can be used to colour fibers. The printingpaste should have a high viscosity, which can be produced with a natural or synthetic thickener.…”

Synthesis of a new series of biologically active dyes containing the sulfa drug nucleus and its use in polyester silk screen printing were presented. Synthesis was performed via azo coupling with C and N Nucleophiles. Spectroscopic tools were used to characterize the synthesized azo derivatives. Also, testing of their printing properties, including fastness to washing, light, rubbing, perspiration, and sublimation were evaluated. The new dyes showed respectable fastness and good antibacterial resistance to the growth of certain species of gram‐positive and gram‐negative bacteria. These low‐cost facile synthesized biologically active dyes could be used for sterilizing textiles.

“…The reaction conditions may act as catalysts, corrosion inhibitors, and intermediates in organic synthesis [9][10][11][12]. In homocyclic and heterocyclic forms, azo compounds (-N=N-) play an essential role in the dye and pigment industries [13][14][15][16]. They have extensively entered the analytical chemistry fields [17,18], indeed into the manufacturing of drugs and other medications [19], and LCD color filters [20].…”

Two new halogenated azo-Schiff ligands were prepared in two steps. The first step included a condensation between 4-amino acetophenone and 2-fluoro-4-bromo aniline to give the corresponding Schiff base. In the second step, the diazonium salt of this Schiff base reacted with 2-naphthol and 4,5-diphenylimidazole to form two new azo-Schiff base derivatives as ligands; (3-((E)-(4-((E)-1-((4-bromo-2-fluorophenyl) imino)ethyl) phenyl) diazenyl) naphthalen-2-ol (HSBAN) (L1) and ((E)-N-(4-bromo-2-fluorophenyl)-1-(4-((E)-(4,5-diphenyl-1H-imidazol-2-yl)diazenyl) phenyl) ethan-1-imine) (HSBAI) (L2), respectively. These new ligands were characterized by mass spectrometry, FT-IR, 1H NMR, UV-Visible spectroscopy and elemental microanalysis (CHN). Five divalent transition metal ion complexes (Co, Ni, Cu, Cd, and Hg) were prepared and characterized, beyond the determination of the optimal condition (concentration, pH value, and the mole ratio M:L) using UV-visible studies. Additionally, complementary techniques, such as atomic absorption, electrical conductivity and magnetic susceptibility, were performed to deduce their geometries. The comprehensive study suggested an octahedral geometry for all complexes except Cd and Hg complexes of the first ligand.

Selenolanes, Selenatrans and Esters of Selenic Acid

It is known that selenic acid and selenium dioxide act as oxidizing agents in reactions with α-oxides when heated. The proposed paper presents data on the synthesis of organoselenium compounds based on reactions of α-oxides with selenic acid and its anhydride, where the latter act as selenation agents. It was found that in the presence of catalytic amounts of boron trifluoride esterate in the reactions of oxiranes with acid the oxirane ring opens both according to the rule and against the Krasussky rule with the formation of a mixture of α- and β- isomers of selenic acid esters. In contrast to the acid, the reactions of oxiranes with selendioxide involve the expansion of the oxirane ring to form functionally substituted selenolanes. This paper is followed by the analysis of the literature material on atranes, a unique class of heterocyclic compounds with distinct biologically active properties, and their element derivatives (B, Ge, Si, etc.). For the first time we have synthesized selenatranol, which is not described in the literature. In future it may not only possess bioactive properties in itself, like the majority of organoselenium compounds, but also be a drug precursor. Acetylselenatranol was synthesized by the reaction of selenatranol with acetic anhydride in acid medium. The data of IR, PMR spectra and elemental analysis of the synthesized compounds as well as the data of thermogravimetric (TGA) and differential thermal analysis (DTA) of some of them are given
