Gold nanoparticle catalysts are important in many industrial production processes. Nevertheless, for traditional Csp2-Csp2 cross-coupling reactions they have been rarely used and Pd catalysts usually give a superior performance. Herein we report that in situ formed gold metal nanoparticles are highly active catalysts for the cross coupling of allylstannanes and activated alkylbromides to form Csp3-Csp3 bonds. Turnover numbers up to 29 000 could be achieved in the presence of active carbon as solid support, which allowed for convenient catalyst recovery and reuse. The present study is a rare case where a gold metal catalyst is superior to Pd catalysts in a cross-coupling reaction of an organic halide and an organometallic reagent.

Enantiopure secondary alcohols are fundamental high-value synthetic building blocks. One of the most attractive ways to get access to this compound class is the catalytic hydroboration. We describe a new concept for this reaction type that allowed for exceptional catalytic turnover numbers (up to 15 400), which were increased by around 1.5-3 orders of magnitude compared to the most active catalysts previously reported. In our concept an aprotic ammonium halide moiety cooperates with an oxophilic Lewis acid within the same catalyst molecule. Control experiments reveal that both catalytic centers are essential for the observed activity. Kinetic, spectroscopic and computational studies show that the hydride transfer is rate limiting and proceeds via a concerted mechanism, in which hydride at Boron is continuously displaced by iodide, reminiscent to an S(N)2 reaction. The catalyst, which is accessible in high yields in few steps, was found to be stable during catalysis, readily recyclable and could be reused 10 times still efficiently working.

In this work, using DFT calculations, we investigated Lewis acidities of carbon (in activated carbonyl group) in comparison to the B(C6F5)(3) in combination with dioxane as the Lewis base (LB) for metal-free catalysis of heterolytic H-2 splitting and hydrogenation of carbonyl compounds. We found that in case of carbon as the Lewis acid (LA) the reaction is controlled by frontier molecular orbital interactions between the H-2 and LA-LB fragments at shorter distances. The steric effects can be reduced by electrophilic substitutions on the carbonyl carbon. Synergic combination between stronger orbital interactions and reduced steric effects can lower the barrier of the H-2 splitting below 10 kcal/mol. With the B(C6F5)(3), the H-2 splitting is controlled by electrostatic interactions, which cause to form an early transition state. An advantage of employing Lewis acidity of the activated carbonyl carbon for hydrogenation is that the hydride-type attack and hydrogenation of the C=O bond occur in a single step throughout H-2 splitting. Hence, stronger Lewis acidity of the C(C=O) reinforces hydrogenation without prohibition of the hydride delivery.

Developing efficient and selective strategies to approach complex architectures containing (multi)stereogenic centers has been a long-standing synthetic challenge in both academia and industry. Catalytic cascade reactions represent a powerful means of rapidly leveraging molecular complexity from simple feedstocks. Unfortunately, carrying out cascade Heck-type reactions involving unactivated (tertiary) alkyl halides remains an unmet challenge owing to unavoidable beta-hydride elimination. Herein, we show that a modular, practical, and general palladium-catalyzed, radical three-component coupling can indeed overcome the aforementioned limitations through an interrupted Heck/allylic substitution sequence mediated by visible light. Selective 1,4-difunctionalization of unactivated 1,3-dienes, such as butadiene, has been achieved by employing different commercially available nitrogen-, oxygen-, sulfur-, or carbon-based nucleophiles and unactivated alkyl bromides (>130 examples, mostly >95:5 E/Z, >20:1 a). Sequential C(sp(3))-C(sp(3)) and C-X (N, O, S) bonds have been constructed efficiently with a broad scope and high functional group tolerance. The flexibility and versatility of the strategy have been illustrated in a gram-scale reaction and streamlined syntheses of complex ether, sulfone, and tertiary amine products, some of which would be difficult to access via currently established methods.

Polymeric graphitic carbon nitride (g-C3N4) supported CuBr2 hybrid material (CuBr2@g-C3N4) was developed by impregnation of CuBr2 on g-C3N4 sheets. The morphology and physiochemical properties were analyzed by powder XRD, SEM, and HRTEM studies. The hybrid CuBr2@g-C3N4 material showed excellent selectivity in the aerobic oxidation of primary/secondary alcohols and benzoins to the corresponding carbonyl compounds in absence of any oxidizing agents. Further, CuBr2@g-C3N4 demonstrated direct oxidation of toluene derivatives to corresponding aldehydes in excellent yields. The g-C3N4 support provides excellent stability and heterogeneity to CuBr2 and was recovered simply by filtration and reused for ten times without appreciable loss in catalytic activity.

In this article, halloysite nanoclay (Hal) was used as porogen for the synthesis of nitrogen doped porous carbon material with high specific surface area and pore volume. To this purpose, polymerization of melamine and terephthalaldehyde (MT) was performed in the presence of amine-functionalized carbon coated Hal (Hal@Glu-2N) that was prepared from hydrothermal treatment of Hal and glucose. Then, the prepared nanocomposite was palladated and carbonized to afford Pd@Hal@C. To further improve the textural properties of the nanocomposite, and introduce more pores in its structure, Hal nanotubes were etched. The characterization of the resulting compound, Pd@C, and comparing it with Pd@Hal@C, showed that etching of Hal significantly increased the specific surface area and pore volume in Pd@C. Pd@C was successfully used as a heterogeneous catalyst for promoting hydrogenation of nitroarens in aqueous media using hydrogen with atmospheric pressure as a reducing agent. The comparison of the structural features and catalytic activity of the catalyst with some control catalysts, including, Pd@Hal, Pd@Hal@Glu, Pd@Hal@Glu-MT and Pd@Hal@C confirmed that nitrogen groups in C could improve the Pd anchoring and suppress its leaching, while etching of Hal and introduction of more pores could enhance the catalytic activity through facilitating the mass transfer.

A series of novel chalcone derivatives pyrido[4,3-b]pyrazin-5(6H)-one (10a-j) were designed, synthesized and their structures were confirmed by H-1 NMR, C-13 NMR and mass spectral data. Further, all derivatives were tested for their anticancer activities against five human cancer cell lines such as MCF-7 (breast cancer), A-549 (lung cancer), Colo-205 (colon cancer), A2780 (ovarian cancer) and DU-145 (prostate cancer) by employing MIT assay. The clinically used drug etoposide was used as standard reference and the anticancer activity was expressed as the IC50 in mu M. Among the ten compounds examined compounds, 10b, 10c, 10d, 10h, and 10i possessed more promising anticancer activity. A molecular docking study implying ATR kinase was carried out to observe the binding mode of chalcone derivatives pyrido[4,3-b]pyrazin-5(6H)-one (10a-j) on the active site of ATR kinase. The most promising compound, 10h showed pi – pi stacking interaction of trimethoxy phenyl and pyridone moiety with the residue Trp850, while the carbonyl (alpha,beta-unsaturated carbonyl) and methoxy functions showed H-bond interaction with the residue Ser773 and Thr856 respectively.
