The adsorption behavior of zinc(II) dimethyldithiocarbamate (Ziram) was studied on the surface of a poly‐o‐toluidine Zr(IV) phosphate nanocomposite cation exchanger. A spectrophotometric method based on the conversion of Ziram into a copper dimethyldithiocarbamate complex was applied for the s...
A double-decrease strategy is described for ultrasensitive determination of the fungicide and vulcanization additive ziram. The assay principle is inspired by the interaction of ziram with gold nanoparticles (AuNPs). In this process, zinc ions are released, and ziram adsorption induces the aggre...
A simple and sensitive capillary electrophoretic method was developed for the separation and determination of Ziram and Zineb in boric acid buffer by direct UV absorbance detection at λ=254 nm. The separation is dependent on pH and nature of the buffer. The detection limits (S/N=3) are 1.88x10 ...
A novel analytical technique for the determination of tetramethylthiuram disulfide (TMTD) was developed. It is based on total oxidation of TMTD with hypobromite. Hypobromite is generated on one segment of interdigitated array. It reacts rapidly and quantitatively with TMTD and unreacted flux of ...
We have developed a method for synthesis of aryl isothiocyanates by means of thiocarbamoylation of aromatic amines by tetramethylthiuram disulfide followed by degradation of the intermediate N(1)-aryl-N,N-dimethylthiourea by concentrated HCl. We have shown that thiocarbamoylation of 4-amino-5-et...
The fungicide thiram (tetramethylthiuram disulfide, TMTD) was administered by repeated oral intubations to groups of male B6C3F 1 mice at 100, 300 and 900mg/kg body weight for 4 consecutive days, or at 300mg/kg for 8 and 12days. 24hr after the last treatment animals were killed, and sple...
The quantitative characteristics of the temperature effect on the rheological properties of aqueous solutions of the anionic surfactant sodium methyl oleyl taurate (SMOT) are presented. An increase in the intensity of thermal motion of surfactant molecules on heating from 25 to 45 °С was shown...
UV-induced photoreactions of 4-chlororesorcinol (4-chloro-1,3-benzenediol; denoted as Cl-RN) and 4,6-dichlororesorcinol (4,6-dichloro-1,3-benzenediol; denoted as Cl-RN-Cl) in low-temperature argon matrices have been investigated by infrared (IR) spectroscopy and density-functional-theory (DFT) c...
The goal of this preliminary study was to produce a promising alternative tool for the direct, rapid and specific determination of vitamin C (VC) content in real samples of different agricultural crops without pre-treatment. For this purpose, a VC electrochemical biosensor based on one-step immo...
Certain mixtures of chemicals are known to synergistically enhance skin permeability to drugs. Here, we report on the transport enhancing properties of mixtures of an anionic surfactant, sodium lauroylsarcosinate (NLS) and a non-ionic surfactant, sorbitan monolaurate (S20) in 1:1 phosphate buffe...
The interaction of sodium N-lauroylsarcosinate (SLS) with N-cetylpyridinium chloride (CPC) and N-dodecylpyridinium chloride (DPC) was investigated in aqueous mixtures. A strong interaction between the anionic and cationic surfactants was observed. The interaction parameter, β was determined for...
1,5-Benzo[b]- and 1,5-naphtho[2,3-b]diazepines were synthesized by the reaction of lithium 1,3-diketonates with 1,2-diaminobenzene and 2,3-diaminonaphthalene in an MeOH-AcOH-HCl mixture at 0 °C. The reactions of fluoroalkyl-containing lithium 1,3-diketonates with 1,2-diaminobenzene and 1,2-diam...
A novel copper(II) mediated tandem reaction was developed for the synthesis of 2-aroylbenzothiazoles from readily available aryl–alkyl ketones in the presence of oxygen in ethanol. This method is mild, operationally simple, makes the use of inexpensive CuBr2 as mediator, and affords the corresp...
A copper(I) complex of 2-aminobenzenethiol, [Cu(abt)] ∞ (1), has been synthesized and characterized. The crystal structure determination indicates a two-dimensional metallopolymeric network formed by edge and corner sharing [Cu(μ 3 -S)N] coordination tetrahedra wherein the copp...
A series of novel hydrogen-bonded (H-bonded) cross-linking polymers were generated by complexing various proton-donor (H-donor) solar cell dyes containing 3,6- and 2,7-functionalized electron-donating carbazole cores bearing symmetrical thiophene linkers and cyanoacrylic acid termini with a prot...
Crystal adducts of diethyldithiocarbamate complexes of zinc(II) and copper(II) with piperidine (Pip) were synthesized, and their solvated forms with the outer-sphere molecules of benzene, pyridine (Py), and morpholine (Mf) were obtained. Adducts with composition [M(Pip)(Edtc)2] · L (L = Py, Mf)...
Theoretical and experimental bands have been assigned for the Fourier Transform Infrared (FT-IR) and Fourier Transform Raman (FT-Raman) spectra of the bis-(diethydithiocarbamate)Zn(II) complex, [Zn(DDTC) 2 ]. The calculations and spectra interpretation have been based on the DFT/B3LYP me...
Peptide-hormone secretion is partially triggered by Ca 2+ influx through voltage-gated Ca 2+ channels (VGCCs) and gene inactivation of Zn 2+ -sensitive Ca v 2.3-type VGCCs is associated with disturbed glucose homeostasis in mice. Zn 2+ has been implicated ...
