An Efficient and Sustainable Approach to Decarboxylative Cross-Coupling Using Silica Coated Magnetic Copper Nanocatalyst for the Synthesis of Internal Alkynes.

ABSTRACT: A highly efficient magnetically separable copper nanocatalyst has been developed for decarboxylative cross-coupling reaction for the alkynylation of haloarenes using alkynoic acid as a reaction partner. The chemical nature, morphology, size, and magnetic properties of the prepared nanocatalyst were studied by SEM, TEM, EDS, FT-IR, VSM, and ICP techniques. Remarkably, this catalyst represents the first successful copper based heterogeneous system for this type of coupling that provides a low-cost, stable, and environmentally friendly magnetically recoverable entity that can be re-used for seven consecutive runs without appreciable loss in its catalytic performance.

Decarboxylative Hydroalkylation of Alkynes.

Project description:The merger of open- and closed-shell elementary organometallic steps has enabled the selective intermolecular addition of nucleophilic radicals to unactivated alkynes. A range of carboxylic acids can be subjected to a CO2 extrusion, nickel capture, migratory insertion sequence with terminal and internal alkynes to generate stereodefined functionalized olefins. This platform has been further extended, via hydrogen atom transfer, to the direct vinylation of unactivated C-H bonds. Preliminary studies indicate that a Ni-alkyl migratory insertion is operative.

Decarboxylative benzylations of alkynes and ketones.

Project description:Benzyl esters of propiolic and beta-keto acids undergo catalytic decarboxylative coupling when treated with appropriate palladium catalysts. Such decarboxylative couplings allow the benzylation of alkynes without the use of strong bases and/or organometallics. This allows the synthesis of sensitive benzylic alkynes that are prone to undergo isomerizations under basic conditions. Additionally, decarboxylation facilitates the site-specific benzylation of diketones and ketoesters under mild, base-free conditions. Ultimately, the methodology described expands our ability to cross-couple medicinally relevant heterocycles.

Algae-mediated copper nanocatalyst for aerobic oxidation and dye decolourization via sustainable wastewater treatment.

Project description:In recent years, several physicochemical methods have been proposed for decolourising textile dyes; however, few have been adopted by the textile industry because of factors such as high cost, low efficiency, and limited applicability to a wide range of dyes. The current study focuses on synthesising algae-mediated Cu and CuO nanocatalysts (Alg-Cu and Alg-CuO) using natural waste materials from green algae. The synthesised Alg-CuO nanocatalyst was characterised and confirmed using SEM, TEM, UV, FT-IR, XRD, XPS, GC-MS, and TGA. An innovative and efficient technique for decolourising dyes through aerobic oxidation was implemented in industrial wastewater treatment. Various hydroxylamine substrates were successfully transformed into the desired aldehydes using an Alg-CuO nanocatalyst. In the process of aerobic oxidation, 2-(2-amino-ethyl)-aminoethanol can be converted into 2-(2-amino-ethyl)acetaldehyde, resulting in 96% product conversion within 4 min. In addition, the synthesised Alg-CuO nanocatalyst was used to investigate the dye decolourisation process using CBB G250 dye. The Alg-CuO nanocatalyst exhibited excellent decolourisation properties; for 20 min, 85% decolourisation of the CBB G250 dye was achieved. As a result, green synthesis is a viable medium for producing Alg-CuO nanocatalysts with high bond energies for dye decolourisation. Finally, the dye and Alg-CuO nanocatalyst was separated and reused for the following process. This method has been used for industrial wastewater treatment.

Gadolinium-Coated Mesoporous Silica Nanoparticle for Magnetic Resonance Imaging.

Project description:Magnetic resonance molecular imaging can provide anatomic, functional and molecular information. However, because of the intrinsically low sensitivity of magnetic resonance imaging (MRI), high-performance MRI contrast agents are required to generate powerful image information for image diagnosis. Herein, we describe a novel T 1 contrast agent with magnetic-imaging properties facilitated by the gadolinium oxide (Gd2O3) doping of mesoporous silica nanoparticles (MSN). The size, morphology, composition, MRI relaxivity (r 1 ), surface area and pore size of these nanoparticles were evaluated following their conjugation with Gd2O3 to produce Gd2O3@MSN. This unique structure led to a significant enhancement in T 1 contrast with longitudinal relaxivity (r 1 ) as high as 51.85 ± 1.38 mM-1s-1. Gd2O3@MSN has a larger T 1 relaxivity than commercial gadolinium diethylene triamine pentaacetate (Gd-DTPA), likely due to the geometrical confinement effect of silica nanoparticles. These results suggest that we could successfully prepare a novel high-performance T 1 contrast agent, which may be a potential candidate for in-vivo MRI.

MCM-41 supported 2-aminothiophenol/Cu complex as a sustainable nanocatalyst for Suzuki coupling reaction.

Project description:We have developed an innovative mesoporous nanocatalyst by carefully attaching a 2-aminothiophenol-Cu complex onto functionalized MCM-41. This straightforward synthesis process has yielded a versatile nanocatalyst known for its outstanding efficiency, recyclability, and enhanced stability. The structural integrity of the nanocatalyst was comprehensively analyzed using an array of techniques, including BET (Brunauer-Emmett-Teller) for surface area measurement, ICP (Inductively Coupled Plasma) for metal content determination, EDS (Energy-Dispersive X-ray Spectroscopy) for elemental mapping, XRD (X-ray Diffraction) for crystalline structure elucidation, SEM (Scanning Electron Microscopy), EMA (Elemental Mapping Analysis), TEM (Transmission Electron Microscopy), TGA (Thermogravimetric Analysis), FT-IR (Fourier Transform Infrared Spectroscopy), AFM (Atomic Force Microscopy), and CV (cyclic voltammetry). Subsequently, the catalytic properties of the newly developed MCM-41-CPTEO-2-aminothiophenol-Cu catalyst was evaluated in the synthesis of biphenyls, demonstrating outstanding yields through a Suzuki coupling reaction between phenylboronic acid and aryl halides. Importantly, this reaction was conducted in an environmentally friendly medium. Note the remarkable recyclability of the catalyst, proving its sustainability over six cycles with minimal loss in activity additionally hot filtration test was prepared to examine the stability of this nanocatalyst. This outstanding feature emphasizes the catalyst's potential for long-term, environmentally conscious catalytic applications.

Copper-catalyzed oxidative cross-dehydrogenative coupling of 2H-chromenes and terminal alkynes.

Project description:An efficient copper-catalyzed cross-dehydrogenative coupling of 2H-chromenes and terminal alkynes mediated by DDQ has been established. A protic additive, EtOH, proved to be crucial for harmonizing the oxidation with a subsequent alkynylation step by retaining the oxidation state of an oxocarbenium ion in the form of acetal. The CDC reaction exhibits a good substrate scope, with a range of terminal aryl- and alkyl alkynes being well tolerated. The copper-catalyzed alkynylation of 2H-chromene acetals with terminal alkynes was also explored.
