Herein we report iodine-mediated multicomponent reactions for the synthesis of naphthoquinone-fused pyrroles tethered with a pyrimidine moiety. The reaction of aryl methyl ketones (3) or terminal aryl alkynes (5) in the presence of molecular iodine in DMSO medium followed by sequential addition of barbituric acids (2) and 2-amino-1,4-naphthoquinone (1) provides the corresponding three-component hybrid molecules 4 having naphthoquinone-fused pyrroles tethered with a barbituric acid moiety. This three-component reaction proceeds via metal-free C-H oxidation followed by multi-component cyclization forming three new bonds (2 C-C, 1 C-N) in one pot. Alternatively, the same molecules can also be prepared from the reaction of arylglyoxals, 2-aminonaphthoquinone, and barbituric acids in the presence of a catalytic amount of iodine in methanol medium under reflux conditions. The salient features of these methodologies are: one-pot metal-free method, good yields, wide substrate scope, easy purification of products, and the presence of medicinally important naphthoquinone, pyrrole and pyrimidine moieties in the products.

Covalent organic frameworks (COFs) are a new class of porous crystalline polymers with a modular construct that favors fiinctionalization. COF pores can be used to grow nanoparticles (nPs) with dramatic size reduction, stabilize them as dispersions, and provide excellent nP access. Embedding substrate binding sites in COFs can generate host-guest synergy, leading to enhanced catalytic activity. In this report, Cu/Cu2O nPs (2-3 nm) are grown on a COF, which is built by linking a phenolic trialdehyde and a triamine through Schiff bonds. Their micropores restrict the nP to exceptionally small sizes (similar to 2-3 nm), and the pore walls decorated with strategically positioned hydrogen-bonding phenolic groups anchor the substrates via hydrogen-bonding, whereas the basic pyridyl sites serve as cationic species to stabilize the [CuclusterCl2](2-) type reactive intermediates. This composite catalyst shows high activity for Glaser-Hay heterocoupling reactions, an essential 1,3-diyne yielding reaction with widespread applicability in organic synthesis and material science. Despite their broad successes in homocoupled products, preparation of unsymmetrical 1,3-diynes is challenging due to poor selectivity. Here, our COF-based Cu catalyst shows elevated selectivity toward heterocoupling product(s) (Cu nP loading 0.0992 mol %; turn over frequency: similar to 4S-50; turn over number: similar to 17S-190). The reversible redox activity at the Cu centers has been demonstrated by carrying out X-ray photoelectron spectroscopy on the frozen reactions, whereas the crucial interactions between the substrates and the binding sites in their optimized configurations have been modeled using density functional theory methods. This report emphasizes the utility of COFs in developing a heterogeneous catalyst for a truly challenging organic heterocoupling reaction.

We prepared high-performance aromatic copolyamides, containing bithiazole and thiazolo-thiazole groups in their main chain, from aromatic diamines and isophthaloyl chloride, to further improve the prominent thermal behavior and exceptional mechanical properties of commercial aramid fibers. The introduction of these groups leads to aramids with improved strength and moduli compared to commercialmeta-oriented aromatic polyamides, together with an increase of their thermal performance. Moreover, their solubility, water uptake, and optical properties were evaluated in this work.

Reduction of various azides using Na2S has been accomplished in water, and, in situ, the resulting amines on reaction with various ketones lead to pyrazolo[3,4-b]pyridines in one pot. Thus, a number of new trifluoromethyl-substituted pyrazolo[3,4-b]pyridine compounds have been prepared and screened for antimicrobial activity against different Gram-positive and Gram-negative strains. A good number of compounds, 4a, 4b, 4d, 4f, 4i, 4k, 4l, 4m, 4r and 4s, were found to possess promising activity. Notably, Na2S on hydrolysis in water generates H2S and NaOH, which facilitate the reduction of azides followed by intramolecular cyclization leading to the title compounds. To the best of our knowledge, this is the first report of the synthesis of the title compounds in aqueous medium in a one-pot reaction.

Alkylidene carbenes undergo rapid inter- and intramolecular reactions and rearrangements, including 1,2-migrations of beta-substituents to generate alkynes. Their propensity for substituent migration exerts profound influence over the broader utility of allcylidene carbene intermediates, yet prior efforts to categorize 1,2-migratory aptitude in these elusive species have been hampered by disparate modes of carbene generation, ultrashort carbene lifetimes, mechanistic ambiguities, and the need to individually prepare a series of C-13-labeled precursors. Herein we report on the rearrangement of C-13-alkylidene carbenes generated in situ by the homologation of carbonyl compounds with [C-13]-Li-TMS-diazomethane, an approach that obviates the need for isotopically labeled substrates and has expedited a systematic investigation (C-13{H-1} NMR, DLPNO-CCSD(T)) of migratory aptitudes in an unprecedented range of more than 30 alkylidene carbenes. Hammett analyses of the reactions of 26 differentially substituted benzophenones reveal several counterintuitive features of 1,2-migration in alkylidene carbenes that may prove of utility in the study and synthetic application of unsaturated carbenes more generally.

This paper describes the synthesis, structure, and reactivity of (eta(5)-C5Me5)(2)U(=-P-2,4,6-(Pr3C6H2)-Pr-i)(OPPh3) (2). Compound 2 can be accessed by a salt metathesis reaction of the uranium methyl chloride metallocene (eta(5)-C5Me5)(2)U(Cl)Me (1) with 2,4,6-(Pr3C6H2PHK)-Pr-i in toluene in the presence of Ph3PO at ambient temperature. Furthermore, it reacts as a masked synthon for the divalent uranium fragment (eta(5)-C5Me5)(2)U by elimination of the phosphinidene fragment (2,4,6-(Pr3C6H2P)-Pr-i:) on exposure to small organic molecules such as Ph2S2, Ph2Se2, bipy, ketazines, carbodiimides, diazenes, and organic azides. Nevertheless, it also forms carbodithioates, imido, diiminatos, and metallaaziridines when it is treated with isothiocyanate, nitrites, and isonitriles, respectively. In contrast, after addition of Me,SiN 3 the uranium azido species (eta(5)-C5Me5)(2)U[N(SiMe3)P(2-NHCMe2-4,6-(Pr2C6H2)-Pr-i)N(SiMe3)]-(N-3) (13) is isolated in good yield.

Utilization of abundantly available biomass to develop advanced materials and products has become an utmost priority these days. Herein, we developed a sustainable route for the synthesis of Ni nanoparticles loaded on N-doped carbon nanosheets using underutilized sugarcane bagasse, urea and NiCl2 center dot 6H(2)O as the carbon, nitrogen and Ni source. The synthesized catalyst was characterized using different analytical techniques; FESEM, elemental mapping and HRTEM analysis revealed the formation of flower-like carbon nanosheets containing uniformly distributed nickel nanoparticles with average particle size of 2.4-10 nm. The synthesized nanocatalyst was used for the one-pot reductive amination of different bio-derived aldehydes with the nitroarenes at 100 degrees C for 4 h. The complete conversion of the variety of nitroarenes with the formation of imines and benzimidazole products was obtained under optimized reaction conditions. The catalyst was recyclable up to five times with negligible loss in selectivity towards imines.

Chiral, cationic NHC-iridium complexes are introduced as catalysts for the intramolecular hydroamination reaction of unactivated aminoalkenes. The catalysts show high activity in the construction of a range of 5- and 6-membered N-heterocycles, which are accessed in excellent optical purity, with various functional groups being tolerated with this system. A major deactivation pathway is presented and eliminated by using alternative reaction conditions. A detailed experimental and computational study on the reaction mechanism is performed providing valuable insights into the mode of action of the catalytic system and pointing to future modifications to be made for this catalytic platform.

A palette of commonly used directing groups, including various pharmaceutically relevant nitrogen-containing heterocycles, are quantitatively ranked based on the results of intermolecular hydrogen isotope exchange competition reactions using two iridium complexes: [Ir(COD)(IMes)(PPh3)][BArF24] and [IrCl(COD)(IMes)]. The directing group power scales that have been constructed from these data reveal a wide range of reactivity covering four orders of magnitude. Intramolecular competition experiments have demonstrated that the obtained reactivity scale provides accurate predictions of regioselectivity within molecules with multiple competing directing groups. This work contributes to our understanding and control of regioselectivity in metal-catalysed C-H activation reactions.
