One of the hypervalent iodines most widely used as an oxidizing agent in organic chemistry is (diacetoxyiodo)benzene (PhI(OAc)2), also known (DAIB), phenyliodine(III) diacetate (PIDA). In this septennial mini-review, authors have concisely and systematically presented representative applications PIDA synthesis involving C-H functionalization, hetero-hetero bond formations, heterocyclic ring con...

We previously reported that if murine leukemia virus particles are produced in the presence of the mild oxidizing agent disulfide-substituted benzamide-2, they fail to undergo the normal process of virus maturation. We now show that treatment of these immature particles with a reducing agent (dithiothreitol) induces their maturation in vitro, as evidenced by proteolytic cleavage of Gag, Gag-Pol...

A new concept of three-dimensional imaging of tumor cell spheroids by light sheet-based fluorescence microscopy and nanosecond ratio imaging is described. Due to its low light dose and alternative excitation by two laser wavelengths (391 and 470 nm), this method maintains cell viability and permits recording of real-time kinetics. A genetically encoded sensor permits measurement of the redox st...

The investigation of chemical co-polymerization aniline and ortho nitroanilinein acidic medium was done. Ammonium persulphate (APS) acted as the oxidizing agent. Synthesis PANI its copolymer done followed by characterization using FTIR analysis to assess bonding pattern. Detection copolymer, crystallinity orientation achieved XRD technique. To determine heat resistance TGA employed. One promine...

This paper describes results of a detailed literature review of the organic and inorganic by-products that have been identified as being formed in aqueous solution with four of the strong oxidizing/disinfecting agents commonly employed in drinking water treatment. These agents are: chlorine, chlorine dioxide, chloramine, and ozone. Significant findings include the production of similar nonchlor...

We report that the photodeoxygenation of 1,2-benzodiphenylene sulfoxide, 1, generates an intermediate capable of oxidizing the solvent benzene to phenol. The reactivity of the intermediate was probed with various substrates (2-methylbutane, chloride ion, and para-substituted aryl sulfides). The intermediate produced in the sulfoxide photodeoxygenation displays an electrophilic oxidation chemist...

Propylene oxide is a crucial feedstock in the plastic industry. The direct epoxidation of propylene using O2 considered among most promising means producing oxide. Here we report an integrated photo-electro-heterogeneous catalytic system for with O2. Bismuth vanadate (or TiO2) photocatalyst and Co-based electrocatalyst produces H2O2. A titanium silicalite-1 heterogeneous catalyst subsequently e...

Fe(VI) is an unusual and strongly oxidizing form of iron, which provides a potentially less hazardous water-purifying agent than chlorine. A novel on-line electrochemical Fe(VI) water purification methodology is introduced. Fe(VI) addition had been a barrier to its effective use in water remediation, because solid Fe(VI) salts require complex (costly) syntheses steps and solutions of Fe(VI) dec...

Metal-assisted chemical etching of silicon is an electroless method that can produce porous silicon by immersing metal-modified silicon in a hydrofluoric acid solution without electrical bias. We have been studying the metal-assisted hydrofluoric acid etching of silicon using dissolved oxygen as an oxidizing agent. Three major factors control the etching reaction and the porous silicon structur...
