The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 2879-20-1, Name is 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,introducing its new discovery.

A hypercrosslinked polymer (HCP)-immobilized ruthenium catalyst (HCP?PPh3?Ru) was prepared from benzene and triphenylphosphine (PPh3) through a one-step external cross-linking reaction. The structure and composition of the catalyst were fully characterized by many physicochemical methods. HCP?PPh3?Ru was found to possess high Brunauer?Emmett?Teller (BET) surface area, large pore volume, and low skeletal density. Moreover, the Ru catalyst was also featured some advantages, such as low synthetic cost and good chemical and thermal stability. HCP?PPh3?Ru was then used as a recoverable and effective catalyst for the synthesis of 2,4-diaryl-substituted pyridines from acetophenones, ammonium acetate (NH4OAc) and dimethylformamide (DMF), and the cycloaddition reaction of diazodicarbonyl compounds with olefins to afford dihydrofurans. In addition, a combination of HCP?PPh3?Ru and Amberlyst-15 enabled us to establish a simple protocol for the direct synthesis of carbazole derivatives from diazodicarbonyl compound, alkyl vinyl ether and indole. In these selected reactions, the catalyst was easily recovered and reused several times without significant activity loss. (Figure presented.).

Here, biogenic synthesis of Fe2O3@SiO2 nanoparticles using fruit extract of Zanthoxylum rhetsa is reported. The SiO2 nanoparticles was synthesized using paddy straw which is a byproduct obtained in cultivation of rice. The composite was characterised by spectroscopic method like XRD, SEM, TEM and EDX analysis. The ipso-hydroxylation reactions were carried out with excellent yield within a moderate time period with mild reaction condition in all cases. Therefore, this approach may be considered as simple, easy, cheap and greener, environment friendly protocol for ipso-hydroxylation of arylboronic acids at 50 C temperature.

The aim of the research was to investigate the anti-bacterial potential of some N-substituted sulfonamides bearing benzodioxane moiety. The synthesis was started by reaction of N-2,3-dihydrobenzo[1,4]dioxin-6-amine with 4-acetamidobenzene-1-sulfonyl chloride in the presence of 10% aqueous Na2CO3 solution to yield N-(2,3-dihydrobenzo[1,4]-dioxin-6-yl)-4-acetamidobenzenesulfonamide, which was further reacted with alkyl/aralkyl halides in DMF and lithium hydride as a base to afford N-substituted-N-(2,3dihydro-[1,4]-benzodioxin-6-yl)-4-acetamidobenzenesulfonamides. All the synthesized compounds were characterized by spectral data (IR, 1H NMR, EI-MS, and HR-MS). The compounds were tested for antibacterial activity and most of them exhibited potent therapeutic potential against various Gram-negative and Gram-positive strains.
