The oxidation of mono- and diiodo- and -bromo-substituted polymethylbenzenes (mesitylene and durene) in the system PbO2-CF3COOH-CH2Cl2 at room temperature (2-70 h) leads mainly to the formation of iodo- and bromobenzyl alcs. as result of oxidation of Me group. The reaction involves intermediate formation of haloarene radical cations. ESR study of these radical cations made it possible to determine the structure of their singly occupied MOs a2 or b1 and interpret their reactivity.

A method to prepare α-acyl-β-amino acid and 2,2-diacyl aziridine derivatives efficiently from Cu(OTf)2 + 1,10-phenanthroline (1,10-phen)-catalyzed amination and aziridination of 2-alkyl substituted 1,3-dicarbonyl compounds with PhI=NTs is described. By taking advantage of the orthogonal modes of reactivity of the substrate through slight modification of the reaction conditions, a divergence in product selectivity was observed In the presence of 1.2 equiv of the iminoiodane, amination of the allylic C-H bond of the enolic form of the substrate, formed in situ through coordination to the Lewis acidic metal catalyst, was found to selectively occur and give the β-aminated adduct. On the other hand, increasing the amount of the nitrogen source from 1.2 to 2-3 equiv was discovered to result in preferential formal aziridination of the C-C bond of the 2-alkyl substituent of the starting material and formation of the aziridine product.

Kahandal, Sandeep S. published the artcileGreener iodination of arenes using sulphated ceria-zirconia catalysts in polyethylene glycol, Safety of 4-Iodo-3-nitroaniline, the main research area is sulfated ceria zirconia catalyst polyethylene glycol arene iodination.

An environmentally benign method for the selective monoiodination of diverse aromatic compounds has been developed using reusable sulfated ceria-zirconia under mild conditions. The protocol provides moderate to good yields and selectively introduces iodine at the para/ortho position in monosubstituted arenes. SO42-/Ce0.07Zr0.93O2 was found to be the best choice for the synthesis of aryl iodides in high yield, presumably due to the maximum number of acid sites (4.23 mmol g-1) among the various compositions of the catalyst system.

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.

Yusubov, Mekhman S. published the artcilePotassium 4-Iodylbenzenesulfonate: Preparation, Structure, and Application as a Reagent for Oxidative Iodination of Arenes, HPLC of Formula: 2100-25-6, the main research area is potassium iodylbenzenesulfonate preparation arene oxidant.

A new hypervalent iodine(V) compound, potassium 4-iodylbenzenesulfonate, was prepared by the oxidation of 4-iodobenzensulfonic acid with Oxone in water. This potassium salt can be further converted into 4-iodylbenzenesulfonic acid by treatment with the acidic form of Amberlyst 15 in water. A single-crystal X-ray structure of potassium 4-iodylbenzenesulfonate revealed the presence of polymeric chains in the solid state due to a combination of numerous intra- and intermol. interactions. Potassium 4-iodylbenzenesulfonate will likely find many practical applications as a thermally stable and water-soluble hypervalent iodine-based oxidant, particularly useful as a reagent for oxidative iodination of aromatic substrates. This reagent can be effectively recovered from the reaction mixture (92 % recovery) by treatment of the aqueous layer with Oxone at 60°C for 2 h, followed by filtration of the precipitate
