Selective [5 + 1] and [5 + 2] Cycloaddition of Ynamides or Propargyl Esters with Benzo[ d]isoxazoles via Gold Catalysis

Benzo[d]isoxazoles are found to act as novel nucleophiles to undergo gold-catalyzed [5 + 1] or [5 + 2] cycloaddition reactions with ynamides. The reaction provides a concise and chemoselective access to polysubstituted 2H-benzo[e][1,3]oxazines or benzo[f][1,4]oxazepines. In addition, benzo[d]isoxazoles can also react with gold-carbene intermediates derived from propargyl esters to afford [5 + 1] annulation products.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 21725-69-9 is helpful to your research. 21725-69-9

Preparation of Reinforced poly (BisGMA-UDMA) Graphene-Based Nanocomposites Via Moderate in Situ SET-LRP

In the present study, cross-linked poly (dimethacrylate- urethane dimethacrylate) [poly (BisGMA-UDMA)] functionalized-graphene oxide nanosheets were prepared via single-electron transfer living radical polymerization (SET-LRP) using the ?grafting from? strategy, under mild conditions. This method first involves the covalent attachment of Br-containing groups onto the surface of grapheme sheets to give the initiating-groups-containing graphene (G-Br). After that, the succeeding SET-LRP polymerization in DMSO in the presence of a Cu wire/Me6TREN catalytic system at room temperature leads to the grafting of poly (BisGMA-UDMA) chains onto the graphene surface. The resulting graphene-poly (dimethacrylate- urethane dimethacrylate) (G-PDMA-UDMA) nanocomposites were characterized using FT-IR, XRD, DSC, AFM, FE-SEM, and TEM analysis techniques. It was proved that polymer chains were successfully introduced to the surface of the graphene planes. After grafting with poly (BisGMA-UDMA), the dispersibility of the modified GO sheets significantly improved. When compared to G-PDMA, the resulting G-PDMA-UDMA nanocomposite revealed around 75%, 97%, and 65%, increase in compressive strength, Young’s modulus and toughness, respectively. Such smart graphene-based nanocomposites can be used as promising biomaterials in orthopaedic and dental applications with the desired mechanical properties.

Photochemistry of matrix-isolated 3-chloro-1,2-benzisoxazole: Generation and characterization of 2-cyanophenoxyl radical and other reactive intermediates

Photochemistry of 3-chloro-1,2-benzisoxazole 1 in N2 and Ar matrices at 10 K leads to N-chloro-ketenimine 3 and 2-cyanophenyl-hypochlorite 4. The reaction kinetics and the observed photoisomerization of 3 to 4 indicate that ketenimine 3, possibly formed via an elusive vinylnitrene VN, is an intermediate in the formation of hypochlorite 4. A new pathway involving the formation of 2-cyanophenoxyl radical 5, which was captured only in Ar matrix, was also observed. Radical 5 is possibly formed via photodetachment of Cl atom from 1 (or VN) and might explain the formation of 3-chloro-6-oxocyclohexa-1,4-dienecarbonitrile 2 in N2 and Ar matrices. All the species were characterized by IR spectroscopy and theoretical calculations. The computed geometric and electronic structure of radical 5 is discussed. Overall, the results provided further insight into the mechanism of the photochemistry of 1,2-benzisoxazoles and allowed characterization of new interesting reactive intermediates.
