An efficient, inexpensive and environmentally friendly synthesis of beta-ketosulfones, via NaI-catalyzed oxidative sulfonylation of ketones with zinc sulfinates, employing ethylene dibromide (EDB) and air as the oxidants, is described. EDB was shown to be a mild organic oxidant to convert NaI into molecular iodine that promote the cross-coupling reactions of zinc sulfinates with ketones, producing beta-ketosulfones. Mechanistic studies indicated that a radical pathway might be involved in the reaction process. The key feature of the present protocol is the far greater solubility of NaI and sulfinates in micellar arrays present in aqueous solution where the oxidative coupling reactions are taking place.

The ketones was successfully prepared from secondary alcohols using 9-azabicyclo[3.3.1]nonane-N-oxyl (ABNO) as the catalyst and 2,6-lutidine as the base in acetonitrile solution. The electrochemical activity of ABNO for oxidation of 1-phenylethanol was investigated by cyclic voltammetry, in situ Fourier transform infrared spectroscopy (FTIR) and constant current electrolysis experiments. The resulting cyclic voltammetry indicated that ABNO exhibited much higher electrochemical activity when compared with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) under the similar conditions. A reasonable reaction mechanism of the electrocatalytic oxidation of 1-phenylethanol to acetophenone was proposed. In addition, a series of secondary alcohols could be converted to the corresponding ketones at room temperature in 80-95% isolated yields.

Although compounds with a 2-benzoylbenzoxazole motif are biologically relevant, there are only a few methods for synthesizing them, most of which relied on multistep process or required substrates bearing activating groups. Herein, we report an efficient method for the synthesis of such compounds by direct reactions of o-aminophenols with acetophenones promoted by sulfur in DMSO. The reaction was found to proceed via a Willgerodt rearrangement-type benzoxazolation of acetophenones followed by a benzylic oxidation to reinstall the carbonyl function. This method has a broad substrate scope and good tolerance for sensitive functional groups.

A scalable synthetic method is described for both the preparation of ultrasmall palladium nanoparticles and their subsequent use in catalyzing an alpha-arylation reaction of nitriles in aqueous micelles. This method involves the intermediacy of carbanions or keteniminates, which are presumably stabilized by the micellar environment rather than being quenched with water. These Pd nanoparticles are thoroughly characterized. Mechanistic studies using P-31 NMR spectroscopy revealed the binding of phosphine ligand with the Pd surface and control experiment confirmed the zero-oxidation state of palladium. The scope of the transformation is demonstrated over 35 examples, including one at 50 g scale.

With an intention of identifying chalcone derivatives exhibiting anti-protozoal activity, a cohort of relatively unexplored arylpyrrole-based chalcone derivatives were synthesized in moderate to good yields. The resultant compounds were evaluated in vitro for their potential activity against a cultured Trypanosoma brucei brucei 427 strain. Several compounds displayed mostly modest in vitro anti-trypanosomal activity with compounds 10e and 10h emerging as active candidates with IC50 values of 4.09 and 5.11 mu M, respectively. More importantly, a concomitant assessment of their activity against a human cervix adenocarcinoma (HeLa) cell line revealed that these compounds are non-toxic.

Name: 1-(4-Nitrophenyl)ethanone. Thiruvengetam, P; Chakravarthy, RD; Chand, DK in [Thiruvengetam, Prabaharan; Chakravarthy, Rajan Deepan; Chand, Dillip Kumar] Indian Inst Technol Madras, Dept Chem, Chennai 600036, Tamil Nadu, India published A molybdenum based metallomicellar catalyst for controlled and chemoselective oxidation of activated alcohols in aqueous medium in 2019, Cited 81. The Name is 1-(4-Nitrophenyl)ethanone. Through research, I have a further understanding and discovery of 100-19-6.

A surfactant based oxodiperoxo molybdenum complex, which could activate molecular oxygen, has been employed as a catalyst for controlled oxidation of benzylic alcohols to corresponding carbonyls. The oxidation reactions were carried out under aqueous environment, however, in the absence of any extraneous base or co-catalyst. Sensitive/oxidizable functional groups like cyano, sulfide, hydroxyl, aryl-hydroxyl, alkene (internal/terminal), alkyne (internal/terminal), and acetal were tolerated during the transformations. Such selectivity is attributed to the mild nature of the catalyst. The methodology could also be scaled-up for multi-gram synthesis and the protocol is likely to find practical use since it requires an inexpensive recyclable-catalyst and easily available oxidant (under green conditions). A plausible mechanism is proposed with the help of preliminary computational study. (C) 2019 Elsevier Inc. All rights reserved.

Although alkynes have been extensively exploited in [2 + 2 + 2] cycloadditions with nitriles to form N-heterocyclic aromatics, the alkyne-like metal carbon triple bond has never been used in [2 + 2 + 2] cycloadditions with nitriles. We demonstrate the synthesis of the first metallapyrazine through [2 + 2 + 2] cycloaddition reactions of a metal carbyne complex with nitriles. Experimental observations and density functional theory calculations are evidence for the aromatic character of the metallapentalenopyrazine.

We report an iodoarene-catalyzed enantioselective synthesis of beta,beta-difluoroalkyl bromide building blocks. The transformation involves an oxidative rearrangement of alpha-bromostyrenes, utilizing HF-pyridine as the fluoride source and m-CPBA as the stoichiometric oxidant. A catalyst decomposition pathway was identified, which, in tandem with catalyst structure-activity relationship studies, facilitated the development of an improved catalyst providing higher enantioselectivity with lower catalyst loadings. The versatility of the difluoroalkyl bromide products was demonstrated via highly enantiospecific substitution reactions with suitably reactive nucleophiles. The origins of enantioselectivity were investigated using computed interaction energies of simplified catalyst and substrate structures, providing evidence for both CH-pi and pi-pi transition state interactions as critical features.

The synthesis of a series of novel pyrazolylphenanthroimidazoles 6a-6j has been accomplished utilizing a multi-step synthetic protocol, and characterized through physical and spectral techniques. Among them, the molecules possessing para-bromo (6d), para-methyl (6f) and para-nitro (6j) phenyl substituents on the pyrazole scaffold displayed similar anti-inflammatory activity and the one with no substituents on the aryl unit (6a) exhibited the highest anti-inflammatory profile. While investigating the DPPH radical scavenging activity, the synthesized chemical entity with a para-methoxyphenyl group attached at the pyrazole structural motif (6i) revealed the highest activity when compared to the other synthesized molecules. Furthermore, the evaluation of cytotoxic activity of the synthesized molecule (6a) exerted significant activity against both the pancreatic cell lines such as AsPC1 and SW1990. Besides, while performing the molecular docking studies of 6a with B-cell lymphoma 2, an appreciable binding affinity (-9.04 kcal mol(-1)) has been observed. The results of the present examination imply that these chemical entities could be used as efficient intermediates for the construction of biopertinent molecules.
