A palladium complex of a macrocyclic selenium ligand: catalyst for the dehydroxymethylation of dihydroxy compounds.

This report describes the synthesis of a seventeen-membered macrocyclic ring containing ligand (L1) by the reaction of 1,8-bis(2-(chloromethyl)phenoxy)octane with selenium powder. The -palladium dichloride complex (C1) of the macrocyclic selenium ligand was synthesized from its reaction with the Pd(CHCN)Cl precursor. The formation of the ligand and complex was authenticated with the help of various analytical techniques like H and C{H} NMR, HRMS, FTIR, UV-visible spectroscopy, and elemental analysis.

MIL-88B(Fe) MOF modified screen-printed electrodes for non-enzymatic electrochemical sensing of malathion.

An enzyme-free electrochemical approach for ultra-trace quantification of the organophosphate insecticide malathion is proposed in this study. It is premised on screen-printed carbon electrodes modified by the MIL-88B(Fe) metal-organic framework (MOF). A one-pot solvothermal method was used to synthesise MIL-88B(Fe).

Bimetallic Mn/Fe MOF modified screen-printed electrodes for non-enzymatic electrochemical sensing of organophosphate.

This study presents a novel strategy to fabricate an electrochemical sensor based on a screen-printed electrode (SPE) modified by a bimetallic Mn/Fe metal-organic framework (MnFe-MOF) for the direct determination of organophosphate pesticide chlorpyrifos. Square wave voltammetry technique was employed for the electroanalysis, and the limit of detection remained as low as 0.85 nM or 0.
