A CONVENIENT SYNTHESIS AND BIOCIDAL ACTIVITY OF (N-ALKYL/ARYL SULPHONAMIDO)-4H-BENZ [d] OXAZIN-2-ONE DERIVATIVES

Compounds with a 2(H)-1, 4-benzoxazin-3(4H)-one skeleton have attached the attention of phytochemistry researchers since 2, 4-dihydroxy(2H)-1,4-benzoxazin-3(4H) and 2,4-dihydroxy-7-methoxy-(2H)-1,4-benzoxazin3(4H)-one were isolated from plants belonging to the Poaceae family. These compounds exihibit interesting properties11 such as phytotoxic, antimicrobial12, antifeedent, antifungal and insecticidal properties. The reaction of CSI with 2Chlorobenzyl alcohol result in N-chlorosulphonyl derivatives, which show antibacterial potency. Futher, N-chlorosulphonyl derivatives can be easily cyclofunctionalized. This cyclofunctionalization has been exploited in the synthesis of the title compounds (3). Thus, the title compound being oxygen analogues of 1, 3-thiazine derivatives together with N-sulphonamide moiety could be expected to exhibit enhanced bioactivities14-18.

Internal heavy atom effects in phenothiazinium dyes: enhancement of intersystem crossing via vibronic spin-orbit coupling

The effect of substituting the intra-cyclic sulphur of thionine by oxygen (oxonine) and selenium (selenine) on the intersystem crossing (ISC) efficiency has been studied using high level quantum mechanical methods. The ISC rate constants are considerably increased when going from O towards Se while the fluorescence rate constants remain unchanged. For the three dyes, all accessible ISC channels are driven by vibronic spin-orbit coupling (SOC) between pi pi* states. The interplay between the ground and low-lying excited states has been investigated in order to determine the dominant relaxation pathways. In oxonine the relaxation to the ground state after photoexcitation in water proceeds essentially via fluorescence from the S-1(pi(H)pi(L)*) bright state (k(F) = 2.10 x 10(8) s(-1)), in agreement with the high experimental fluorescence quantum yield. In aqueous solution of thionine, the ISC rate constant (k(ISC) similar to 1 x 10(9) s(-1)) is one order of magnitude higher than fluorescence (k(F) = 1.66 x 10(8) s(-1)) which is consistent with its high triplet quantum yield observed in water (phi(T) = 0.53). Due to a stronger vibronic SOC in selenine, the ISC rate is very high (k(ISC) similar to 10(10) s(-1)) and much faster than fluorescence (k(F) = 1.59 x 10(8) s(-1)). This suggests selenine-based dyes as very efficient triplet photosensitizers.

Removal of some cationic dyes from aqueous solution by acrylamide- or 2-hydroxyethyl methacrylate-based copolymeric hydrogels

In this study, anionic hydrogels were prepared using a crosslinker (N,N’-methylenebisacrylamide) through a free radical addition reaction in aqueous solutions of neutral acrylamide or 2-hydroxyethyl methacrylate monomer and anionic monomers, mesaconic acid or aconitic acid. Cationic dyes along with safranine (azine-), nile blue (oxazine-) and methylene blue (thiazine-) were selected as models of pollutants, and adsorption of these dyes onto the hydrogels was investigated. To examine the effect of concentration on adsorption, dye solutions prepared with a concentration range of 5-50 mg l (-1) and 0.1 g hydrogel at 25 A degrees C were exposed to the hydrogels until equilibrium was established. Dye adsorption onto the hydrogels was found to be an L type Giles adsorption isotherm. Monolayer sorption capacity and adsorption constant values were calculated from the Langmuir plots. To calculate R-L values, a non-dimensional analysis was used and they were always found to be 0 < R < 1. In other words, the hydrogels were favorable for adsorption of these dyes. Aqueous solutions of dyes were observed to interact with hydrogels in the following order: oxazine > azine > thiazine. Furthermore, the higher the number of carboxyl groups in the hydrogel composition, the higher the adsorbed amount of substance.

Reaction of (2,2,3,3-tetrafluoropropyl)sulfenyl chloride with ethyl acrylate as a route to functionalized enamines and ring substituted 3,4-dihydro-2H-thiazine-1,1-dioxides

An efficient two-step procedure of the preparation of (2,2,3,3-tetrafluoropropyl)sulfenyl chloride from 2,2,3,3-tetrafluoropropyl tosylate has been developed. (2,2,3,3-Tetrafluoropropyl)sulfenyl chloride readily reacted with ethyl acrylate giving the mixture of two regioisomeric products. The oxidation of the major regioisomer with hydrogen peroxide afforded ethyl 2-chloro-3-((2,2,3,3-tetrafluoropropyl)sulfonyl)propanoate. The latter compound was found to react with ammonia and aliphatic primary amines under basic conditions with the formation of the acyclic enamines whereas its reactions with aromatic amines afforded ethyl N-aryl-5-(difluoromethyl)-3,4-dihydro-2H-1,4-thiazine-3-carboxylate-1,1-dioxides.

Chemometric Characterization of Synthetic Dye Sorption onto Slovakian River Sediments: A Laboratory Batch Experiment

The aim of the work was to characterize the sorption of cationic dyes thioflavine T (ThT) and methylene blue (MB) onto selected Slovakian river sediments using chemometric approaches including principal component analysis (PCA) and cluster analysis (CA). Also, the potential of mentioned multivariate analyses for comparison of studied objects (river sediments or river and model waters) as well as in finding relationships between the variables describing the physico-chemical characteristics of studied matrices or waters and sorption/desorption characteristics of matrices for dyes binding under laboratory conditions was evaluated. Parameters describing the physico-chemical characteristics of sediments include: pH, pH(zpc), or cation-exchange capacity; and in the case of waters: pH, conductivity, water hardness, content of dissolved solids or presence of organic compounds. From the comparison of dye sorption onto sediments, it was found that sorption of thiazine dye MB was minimally 1.5-times higher than sorption of benzothiazole dye ThT. Sorption capacities Q(s) reached the maximum values in the case of sediments originated from Dudvah River (MB-Q(s) = 8.70 +/- 0.42 mg g(-1); ThT-Q(s) = 5.03 +/- 0.28 mg g(-1); +/- SD). Obtained results showed that applied methods of multivariate analyses represent a suitable tool for evaluation of sorption/desorption processes of organic xenobiotics binding in sediments.
