Selective amperometric flow-injection analysis of carbofuran using a molecularly-imprinted polymer and gold-coated-magnetite modified carbon nanotube-paste electrode

Herein, we propose a new approach for selective determination of carbofuran (CBF) in vegetables, based on a simple flow-injection system using a molecularly-imprinted amperometric sensor. The sensor design is based on a carbon-paste electrode decorated with carbon nanotubes and gold-coated magnetite (CNTs-Fe3O4@Au/CPE) coated with a molecularly-imprinted polymer (MIP) for CBF sensing. The MIP was synthesized on the electrode surface by electropolymerization using a supramolecular complex, namely 4-ter-butylcalix [8] arene-CBF (4TB[8]A-CBF), as the template. We used o-phenylenediamine as the functional monomer. Our results demonstrate that incorporation of the MIP coating improves the electrochemical catalytic properties of the electrode, increases its surface area, and increases CBF selectivity by modulating the electrical signal through elution and re-adsorption of CBF. The imprinted sensor (MIP-CNTs-Fe3O4@Au/CPE) was used in a flow-injection analysis (FIA) system. Experimental conditions were investigated in amperometric mode, with the following optimized parameters: phosphate buffer solution (0.1 M, pH 8.0) as the carrier, flow rate 0.5 mL min?1, applied potential +0.50 V. When used in the FIA system, the designed imprinted sensor yields a linear dynamic range for CBF from 0.1 to 100 muM (r2 = 0.998) with a detection limit of 3.8 nM (3Sb), and a quantification limit of 12.7 nM (10Sb). The sensor exhibits acceptable precision (%RSD = 4.8%) and good selectivity toward CBF. We successfully applied the electrode to detect CBF in vegetable samples.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: benzofuran, you can also check out more blogs about1563-38-8

Continuous solvent-free synthesis of imines over uip-gamma-Al2O3-CeO2 catalyst in a fixed bed reactor

One-pot synthesis of imines from benzyl alcohols and anilines by heterogeneous catalysis in batch reactor has already been widely studied, but its high cost and low production efficiency limit its application in the fine chemicals industry. In this work, gamma-Al2O3 balls supported CeO2 catalyst (uip-gamma-Al2O3-CeO2) was prepared by a novel unsaturated-impregnation-precipitation method, and was employed as a catalyst for continuous solvent-free synthesis of imines in a fixed bed reactor. Under the optimal technological parameter of fixed bed reactor and reaction condition, uip-gamma-Al2O3-CeO2-500 C obtained remarkable 97 % yield of imine. After 20 days` continuous operation, the total isolated yield of imine and TONBA/CeO2 reached up to 81 % and 16838, respectively. Importantly, the catalyst could be reactivated in situ in the fixed reactor. Through detailed characterization, the extraordinary catalytic performance of uip-gamma-Al2O3-CeO2-500 C can be attributed to the abundant acid sites of gamma-Al2O3 as well as the synergistic effect between CeO2 and gamma-Al2O3.

A versatile catalyst for intermolecular direct arylation of Indoles with benzoic acids as arylating reagents

(Figure Presented) Coupled together: With a versatile catalyst system (Pd(TFA)2/Ag2CO3/propionic acid) both electron-rich and -deficient benzoic acids serve as arylating reagents for the direct functionalization of a wide rage of indoles by a combination of decarboxylation and C-H bond activation. Depending on the nature of the benzoic acids, the reaction occurs selectively at either the C2- or C3-position of indoles, which may arise from two different catalytic pathways (see scheme; TFA = trifluoroacetate).

Diverse asymmetric quinolizidine synthesis: A stereodivergent one-pot approach

A diverse stereodivergent organocatalytic one-pot addition/cyclization/ annulation sequence to optically active quinolizidine derivatives from easily available starting materials is presented. The one-pot sequence relies on a pyrrolidine-catalyzed enantioselective conjugate addition of electron-deficient amide a-carbons to alpha,beta-unsaturated aldehydes, spontaneous hemiaminal formation and acid-catalyzed/mediated N-acyliminium ion cyclization to give the quinolizidine framework. Simple tuning of the reaction conditions in the N-acyliminuim ion cyclization step provides a diastereomeric switch, which gives access to both of the two bridgehead epimers through kinetic, thermodynamic or chelation control. The methodology display a broad substrate scope that is demonstrated by the stereoselective formation of indolo-, thieno-, benzofuro-, furo- and different benzoquinolizidine derivatives with high atom efficiency, up to >99% ee and up to >95:5 dr. Due to its efficiency, synthetic diversity and operational simplicity, this protocol has the potential to find important use as a key step in natural product synthesis, biochemistry and pharmaceutical science. The stereochemical outcome of the one-pot sequence was investigated, and the mechanism and origin of stereoselectivity of the different steps is discussed.
