Gould, J. P. published the artcileKinetics of the heterogeneous ozonation of nitrated phenols, Formula: C6H4INO3, the main research area is nitrophenol ozonization water wastewater.

The kinetics of the heterogeneous ozonization of PhOH and 27 nitrophenols representing a wide array of functional groups was studied. In the systems examined, the process was of zero order with respect to phenolic concentration, which indicates mass transfer as the prime control on the process. Anal. of the 1st-order rate constants permitted computation of overall mass transfer coefficients for all compounds The coefficients were 60% lower than the kLa (where kL = liquid mass transfer coefficient and a = sp. interfacial surface area) values measured by others in water and showed very little variation regardless of chem. structure of the phenol. Efforts at development of a QSAR model for the kinetics were fruitless.

Saikia, L. published the artcileRegiospecific Oxyhalogenation of Aromatics Over SBA-15-Supported Nanoparticle Group IV-VI Metal Oxides, Recommanded Product: 4-Iodo-2-nitrophenol, the main research area is aromatic compound oxyhalogenation metal oxide catalyst silica support.

TiOx, VOx, MoOx and WOx supported on SBA-15 exhibit efficient catalytic activity for oxyhalogenation of aromatics with the H2O2-halide ion system. Unlike the hitherto known solid catalysts, these reusable catalysts yield the para-halogenated product with 100% selectivity at 298 K and moderate acidic pH (3-5). The catalytic activity was enhanced by five orders of magnitude when supported on SBA-15.

Hutton, Harold M. published the artcileDetermination of substituent effects by factor analysis and multiple linear regression for the carbon-13 nuclear magnetic resonance chemical shifts in 4-substituted phenols and 2-nitrophenols, Product Details of C6H4INO3, the main research area is LFER NMR phenol derivative.

13C NMR chem. shifts are reported for a series of 4-substituted phenols and 2-nitrophenols in Me2SO. For chem. shift correlations, it was found by factor anal. and iterative multiple linear regression that the para chem. shifts require two substituent factors whereas the ipso, ortho, and meta chem. shifts require 3 factors. Regression analyses were performed using the field and resonance parameters (σF, σR0) and the appropriate ipso, ortho, and meta parameters determined by Reynolds. Good correlations were obtained except for the 3 meta carbon analyses, where the correlation coefficients range from 0.877 to 0.963.

Zhang, Wei published the artcilePalladium-Catalyzed Aromatic C-H Bond Nitration Using Removable Directing Groups: Regiospecific Synthesis of Substituted o-Nitrophenols from Related Phenols, Application In Synthesis of 21784-73-6, the main research area is pyridinyloxyphenol regiospecific nitration palladium catalyst; nitrophenol preparation.

A general and regiospecific transformation of substituted phenols into the related o-nitrophenols has been achieved via a three-step process involving the palladium-catalyzed chelation-assisted ortho-C-H bond nitration as the key step. In the process, 2-pyridinyloxy groups act as removable directing groups for the palladium-catalyzed ortho-nitration of substituted 2-phenoxypridines, and they can be readily removed in the subsequent conversion of the resulting 2-(2-nitrophenoxy)pyridines into 2-nitrophenols.

A wide range of aromatic compounds (e.g., C6H6) have been effectively iodinated with a pyridine-iodine monochloride complex (I). Condensed polycyclic iodides, which are not readily obtained via direct iodination, can be prepared indirectly via their corresponding organomercurials in 1 step. Some benzoid and nonbenzoid heterocycles (e.g., indole) are iodinated with I.

Palav, Amey published the artcileNCBSI/KI: A Reagent System for Iodination of Aromatics through In Situ Generation of I-Cl, Safety of 4-Iodo-2-nitrophenol, the main research area is arene chlorophenylsulfonyl benzenesulfonamide potassium iodide iodination green chem; iodoarene preparation.

In-situ iodine monochloride (I-Cl) generation followed by iodination of aromatics using NCBSI/KI system was developed. The NCBSI reagent required no activation due to longer bond length, lower bond dissociation energy, and higher absolute charge d. on nitrogen. The system was adequate for mono- and diiodination of a wide range of moderate to highly activated arenes with good yield and purity. Moreover, the precursor N-(benzenesulfonyl)benzenesulfonamide was recovered and transformed to NCBSI and made the protocol eco-friendly and cost-effective.

Juarez-Ornelas, Kevin A. published the artcileIodine(III)-Catalyzed Electrophilic Nitration of Phenols via Non-Bronsted Acidic NO2+ Generation, Recommanded Product: 4-Iodo-2-nitrophenol, the main research area is nitrophenol preparation iodine catalyzed electrophilic nitration phenol.

The first catalytic procedure for the electrophilic nitration of phenols was developed using iodosylbenzene as an organocatalyst based on iodine(III) and aluminum nitrate as a nitro group source. This atom-economic protocol occurs under mild, non-Bronsted acidic and open-flask reaction conditions with a broad functional-group tolerance including several heterocycles. D. functional theory (DFT) calculations at the (SMD:MeCN)Mo8-HX/(LANLo8+f,6-311+G*) level indicated that the reaction proceeds through a cationic pathway that efficiently generates the NO2+ ion, which is the nitrating species under neutral conditions.

Misal, Balu published the artcileSulfated polyborate-H2O assisted tunable activation of N-iodosuccinimide for expeditious mono and diiodination of arenes, Application In Synthesis of 21784-73-6, the main research area is arene iodosuccinimide sulfated polyborate catalyst regioselective iodination; iodoarene preparation.

Owing to both Lewis and Bronsted acid active sites on sulfated polyborate under homogeneous conditions, iodination protocol of arenes was developed, which can meet the requirement of regioselectivity and higher yield. The sulfated polyborate activated N-iodosuccinimide for mono iodination of highly activated substrates viz. phenols, anilines under anhydrous condition. Water tuned sulfated polyborate to generate more Bronsted acid sites resulting in rapid activation of NIS for diiodination. The protocol was equally applicable to diiodination of 4-hydroxyphenylacetic acid to synthesize 4-hydroxy-3,5-diiodophenylacetic acid, an intermediate of tiratricol, a thyroid treatment drug. This protocol was further integrated via one-pot sequential iodination and Sonogashira coupling to synthesize aryl acetylenes, building blocks for the synthesis of a variety of specialty chems., API and natural products.
