Adsorptive removal of thiazine dyes from aqueous solutions by oil shale and its oil processing residues: Characterization, equilibrium, kinetics and modeling studies

Adsorption characteristics of oil shale (OS) and its pyrolysis byproducts for cationic thiazine dyes were investigated using thionine (TH), toluidine blue (TB) and methylene blue (MB). The time dependent data for the OS adsorption were analyzed using the linear driving force (LDF) model by combining with the Langmuir isotherm. The external mass transfer (k(f)) and surface diffusion (D-s) coefficients were analytically calculated based on McKay equation. They decreased with increasing molecular sizes of the dyes in the following order TH > TB > MB. In contrary, desorption efficiency in 0.1 M NaCI solution increased in the same order. The thermogravimetric analysis (TGA/DTG), atomic force microscopy (AFM), diffuse reflectance infrared Fourier transforms (DRIFT) and X-ray diffraction (XRD) spectroscopy techniques were used in conjunction to characterize the OS samples. A comparison of (DRIFT) spectra of the dye loaded and unloaded adsorbents showed that the larger dye molecules are primarily adsorbed on the negatively charged surface hydroxyl groups and/or on organic functional groups with electrostatic interactions while the smaller molecules replace with structural cations in the interlayer space of the mineral matrices. Adsorption capacity of the pyrolysis residue obtained in nitrogen atmosphere at 200 degrees C (OS-200) for the dyes decreased with respect to the OS whereas the byproduct at 500 degrees C (OS-500) had considerably higher adsorption ability. All of the dyes were completely removed by the OS and OS-500 from dilute solutions (<0.5 mmol L-1). The OS-500 was also a good candidate for water remediation due to its high dye removal capacity in concentrated dye solutions. (C) 2015 Elsevier B.V. All rights reserved.

Synthesis, characterization and antimicrobial activity of new chalcones and their 6-aryl-4-(2,5-dichlorothiophen-3-yl)-6H-1,3-thiazin-2-amine derivatives

Chalcones (5a-h) were prepared in high yields via the condensation of 3-acetyl-2,5-dichlorothiophene (3) with aryl aldehydes (4a-h). The reaction of the resulting chalcones with thiourea in the presence of a catalytic amount of hydrochloric acid provided the 1,3-thiazin-2-amine derivatives (6a-g) in moderate yields. All new compounds were characterized by extensive NMR analysis data, including 1D NMR experiments (H-1 and C-13) and 2D NMR experiments (COSY, HMBC, HSQC), as well as ESIMS and HRESIMS data. The newly synthesized compounds were evaluated for their biological activities, which demonstrate a very good to low bioactivities as antibacterial and antifungal, respectively. [GRAPHICS] .

Surface functionalizedCasuarina equisetifoliapine powder for the removal of hetero-polyaromatic dye: characteristics and adsorption

The seed ofCasuarina equisetifolia, the genus of Pinus of the familyPinaceaewas examined for the potentiality of adsorbing a thiazine-based hetero-polyaromatic dye from water system. For which, the surface functionalization ofCasuarina equisetifolia(SFCE) was achieved through H(2)SO(4)acidic bath to treat methylene blue (MB) dye contaminated water. The SFCE was characterised using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) to analyse morphological, physical and chemical behaviour after surface modification. The effects of adsorption process influencing variables such as pH, concentration of MB dye, contact time and temperature was examined. The maximum adsorption capacity of 0.5 gL(-1)SFCE for the concentration ranging from 20 to 100 mgL(-1)of MB was investigated using different variables. The effect of parameters including pH, time and temperature were optimised at a speed of agitation of 150 rpm. The adsorption data retrieved from batch experiments were fit with Langmuir, Freundlich, Temkin and Dubinin-Raduskevich (D-R) isotherm models, and as a result, Freundlich presents the best fit (R-2 > 0.97). Pseudo-second order kinetic was superior indicating that SFCE-MB system has undergone the chemisorption mechanism (R-2 > 0.99) spontaneously. Overall, the tested system with synergistic effect was witnessed with maximum adsorption efficiency of 42.19 mg g(-1)to remove dye from industrial wastewater.

Removal behaviour of a thiazine, an azo and a triarylmethane dyes from polluted kaolinitic soil using electrokinetic remediation technology

In this study, we investigated the potentiality of the electro-kinetic remediation (EKR) technique for the removal of organic dyes polluted soil. Methylene blue (MB), methyl orange (MO), and phenol red (PR) are representing a thiazine, an azo, and a tryarilmethane dye respectively, which was spiked with kaolinite were selected as a model for pollutant dyes tests. An EKR tool (15 cm length) equipped with a DC electric current with the maximum values of 30 V. Graphite electrodes were used for both anode and cathode was set up for two weeks operation. As a result, only 40-55 % of dye was removed from the soil sections by using distilled water. However, by the addition of some electrolytes; the percentage of dyes removed from the soil increased from 73-76 % and 85-89 % for sodium sulphate, and monosodium dihydrogen phosphate, respectively. It resulted that 55-64 % of dyes was removed without controlling the pH. The significant improvement was achieved by controlling the pH of the system. By controlling the pH in the cathode chamber, only 23 % of MB, 25 % of MO, and 18 % of PR dyes remain in the soil sections, respectively. While by controlling the pH in the anode chamber, almost 90 % of tested dyes could be removed from the kaolinite chamber effectively. The movement of a thiazine dye, from the anode to the cathode chamber was controlled by electro-migration and electro-osmosis phenomena. An azo dye transported from the cathode to the anode chamber by a similar process. However, a triarylmethane dye was removed from the soil sections by only electro-osmosis process. For three kinds of tested dyes, it were found that electro-osmotic flow moving from the anode to the cathode directions. The ageing of dye affects the removal percentage of the dye.

N-Radical Initiated Aminosulfonylation of Unactivated C(sp(3))-H Bond through Insertion of Sulfur Dioxide

N-Radical initiated aminosulfonylation of unactivated C(sp(3))-H bond through insertion of sulfur dioxide in the presence of visible light is reported. O-Aryl oximes react with DABCO center dot(SO2)(2) smoothly at room temperature under blue LED irradiation without any metals or photoredox catalysts, generating diverse 5,6-dihydro-4H-1,2-thiazine 1,1-dioxides in good yield. Additionally, this approach can be extended to the synthesis of 1H-benzo[d][1,2]thiazine 2,2-dioxides. During the reaction process, an N-radical is initiated by the treatment of O-aryl oximes with DABC center dot(SO2)(2) under visible-light irradiation. It is followed by aminosulfonylation of a nearby C(sp(3)) H bond through 1,5-hydrogen atom transfer with accompanying insertion of sulfur dioxide to provide 1,2-thiazine 1,1-dioxide derivatives.

Realizing the Trifunctional Potential of Alkyl 4-Chloro-2-diazo-3-oxobutanoates: Convenient Assembly of 6,7-Dihydro-4H-[1,2,3]triazolo[5,1-c][1,4]thiazine Core

The first example of exploiting the trifunctional character of alkyl 4-chloro-2-diazo-3-oxobutanoates in the reactions with vicinal N , S -bis-nucleophiles leading to the formation of bicyclic 6,7-dihydro-4 H -[1,2,3]triazolo[5,1- c ][1,4]thiazines is presented. The key to the successful realization of the atom-economical synthetic strategy is the initial S (N) 2 event, which facilitates the subsequent domino 1,2,3-triazole formation via the Wolff reaction. Equally important is the choice of sodium acetate as the base: acetic acid formed in the course of the initial nucleophilic substitution acts as an efficient catalyst for the Wolff reaction, which suppresses the competing, unwanted fragmentation path (observed when other bases are used).

The Smiles rearrangement in the syntheses of azaphenothiazines. Part II. The review of the various types of phenyl azinyl and diazinyl sulfides undergoing this rearrangement

Azaphenothiazines are one of the most bioactive heterocyclic scaffolds in medicinal chemistry. This review discusses the Smiles rearrangement of over 40 types of phenyl azinyl sulfides and diazinyl sulfides during syntheses of azaphenothiazines. These syntheses consist of two (rearrangement/cyclization) or three steps (sulfide formation/rearrangement/cyclization) proceeding often rapidly without isolation of intermediates. The rearrangement depends on the nature of sulfides, steric hindrance, reaction conditions (basic, but also weakly and strongly acidic, and even neutral and thermal). Some reaction conditions and catalysts favor direct cyclization. This review arranges the knowledge of the Smiles rearrangement of phenyl azinyl and diazinyl sulfides but also systematizes the syntheses of monoaza-, diaza-, triaza-, tetraazaphenothiazines and their benzo- and dibenzo derivatives. The review shows that some formed azaphenothiazines were wrongly identified and not all wrong structures have been corrected. Some syntheses cannot be defined as proceeding with the rearrangement or not when both the rearranged and direct products are the same. The structure analysis of resulted azaphenothiazines is crucial (the most reliable: X-ray analysis or two-dimensional NMR). The authors hope that this review will prompt researchers to revisit some syntheses of azaphenothiazines. (C) 2020 Elsevier B.V. All rights reserved.

Synthesis of Fused 1,2,4-Dithiazines and 1,2,3,5-Trithiazepines

Reacting (Z)-N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-1H-pyrazol-5-amines 5 with Et2NH and then with concd H2SO4 gives 5H-pyrazolo[3,4-e][1,2,4]dithiazine-3-carbonitriles 7 in good yields (74-85%) and 6H-pyrazolo[3,4-f][1,2,3,5]trithiazepine-4-carbonitriles 9 as minor products (0-6%). Furthermore, the 1,3-dimethylpyrazole analogue 5a was transformed into the dithiazine 7a in two discrete steps, allowing the isolation of a disulfide intermediate (Z)-2-[(diethylamino)disulfan-yl]-2-[(1H-pyrazol-5-yl)imino]acetonitrile (8a). The one-pot, two-step reaction also worked with electron-rich hydroxy- and methoxy-substituted anilines. Thermolysis of the pyrazolo[3,4-e][1,2,4]dithiazines 7 gave the ring-contracted 1H-pyrazolo[3,4-d]thiazole-5-carbonitriles 6 (94-100%). With active sulfur, 1,3-dimethyl-5H-pyrazolo[3,4-e][1,2,4]dithiazine-3-carbonitrile (7a) gave 1,3-dimethyl-6H-pyrazolo[3,4-f][1,2,3,5]trithiazepine-4-carbonitrile (9a), but on prolonged reaction times, it gave 5,7-dimethyl-5H-[1,2,3]dithiazolo[4,5-b]pyrazolo[3,4-e][1,4]thiazine (13). Finally, in the absence of acid, heating a solution of (Z)-2-[(diethylamino)disulfanyl]-2-[(1,3-dimethyl-1H-pyrazol-5-yl)imino]acetonitrile (8a) gave 4,6,10,12-tetramethyl-6H-pyrazolo[3,4-f]pyrazolo[3′,4′:4,5]pyrimido[6,1-d][1,2,3,5]trithiazepine-8,12b(10H)-dicarbonitrile (19) (67%).
