Dual Roles of beta-Oxodithioesters in the Copper-Catalyzed Synthesis of Benzo[e]pyrazolo[1,5-c][1,3]thiazine Derivatives

A facile and efficient method for the chemoselective synthesis of benzo [e]pyrazolo [1,5-c] [1,3]thiazine derivatives has been developed by tandem Ullmann Coupling reactions of beta-oxodithioesters (ODEs) with 3-(2-bromoaryl)-1H-pyrazoles in C-S bond formation manner, in which ODEs play dual roles as both a substrate and a ligand. A series of benzo[e]pyrazolo[1,5-c][1,3]thiazine derivatives were provided in good to excellent yields with CuI as the copper source in the presence of NaOH in CH3CN at 80 degrees C Under a N-2 atmosphere.

Characterization and photocatalytic performance evaluation of various metal ion-doped microstructured TiO2 under UV and visible light

Commercially available microcrystalline TiO2 was doped with silver, ferrous and ferric ion (1.0mol %) using silver nitrate, ferrous sulfate and ferric nitrate solutions following the liquid impregnation technology. The catalysts prepared were characterised by FESEM, XRD, FTIR, DRS, particle size and micropore analysis. The photocatalytic activity of the prepared catalysts was tested on the degradation of two model dyes, methylene blue (3,7-bis (Dimethylamino)-phenothiazin-5-ium chloride, a cationic thiazine dye) and methyl blue (disodium;4-[4-[[4-(4-sulfonatoanilino)phenyl]-[4-(4-sulfonatophenyl)azaniumylidenecyclohexa-2,5-dien-1-ylidene]methyl]anilino]benzene sulfonate, an anionic triphenyl methane dye) under irradiation by UV and visible light in a batch reactor. The efficiency of the photocatalysts under UV and visible light was compared to ascertain the light range for effective utilization. The catalysts were found to have the anatase crystalline structure and their particle size is in a range of 140-250nm. In the case of Fe2+ doped TiO2 and Fe3+ doped TiO2, there was a greater shift in the optical absorption towards the visible range. Under UV light, Ag+ doped TiO2 was the most efficient catalyst and the corresponding decolorization was more than 99% for both the dyes. Under visible light, Fe3+ doped TiO2 was the most efficient photocatalyst with more than 96% and 90% decolorization for methylene blue and methyl blue, respectively. The kinetics of the reaction under both UV and visible light was investigated using the Langmuir-Hinshelwood pseudo-first-order kinetic model. Kinetic measurements confirmed that, Ag+ doped TiO2 was most efficient in the UV range, while Fe3+ doped TiO2 was most efficient in the visible range.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 7143-01-3, you can contact me at any time and look forward to more communication. Recommanded Product: Methanesulfonic anhydride.

Synthesis of 2,5-Disubstituted Derivatives of Pyrano[2,3-d][1,3]thiazines via the Interaction of 2-Substituted 4-Hydroxy-6H-1,3-thiazine-6-ones with Aldehydes

A new and efficient route for the synthesis of derivatives of the poorly investigated pyrano[2,3-d][1,3]thiazine heterocyclic system is disclosed. These compounds were prepared via annulation of 2-aryl-4-hydroxy-6H-1,3-thiazine-6-ones with aliphatic and aromatic aldehydes in the presence of pyridine. The method is general and versatile, and the interaction is independent on the nature of the aldehyde, the only exceptions being formaldehyde and salicylaldehydes.

Synthesis of Thiazinoimidazoles by Lewis Acid-Catalyzed [3+3] Cycloaddition Reactions of Propargyl Alcohols with 2-Mercaptoimidazoles

The unique ytterbium-catalyzed generation of sulfur- and selenium-substituted propargylic and allenic cations and their reactions with 2-mercaptoimidazole derivatives were described. The regioselective [3+3] annulation reactions proceeded to give a wide variety of S,N-acetal-containing bicyclic and tricyclic thiazinoimidazoles in good to high yields. Treatment of thiazinoimidazoles with LDA readily underwent ring contraction to afford thiazolobenzimidazoles. Deselenenylation and successive functionalization broaden the scope of accessible thiazinoimidazoles.
