Electrochemical Conversion of the Lignin Model Veratryl Alcohol to Veratryl Aldehyde Using Manganese(III)-Schiff Base Homogeneous Catalysts
Lignin and other colored structures need to be bleached after the Kraft process in the pulp industry. Development of environmentally-safe bleaching catalysts or electrocatalysts constitutes an attractive strategy for ...
Biomimetic Catalysts for Oxidation of Veratryl Alcohol, a Lignin Model Compound
Kraft pulp has to be bleached to eliminate the chromophoric structures, which cause a darkening of the pulp. In Nature, an equivalent role is assumed by ligninolytic enzymes such as lignin peroxidases, manganese peroxidases ...
Modeling the OEC with two new biomimetic models: preparations, structural characterization, and water photolysis studies of a Ba–Mn box type complex and a Mn4N6 Planar-diamond cluster
The oxygen-evolving complex (OEC) is the native enzyme that catalyzes the oxidation of water in natural photosynthesis. Two new classes of manganese cluster complexes of formula Ba2Mn2L12(H3L1)2(CH3OH)4 1 and Mn4L26Cl2 2 ...
Synthesis of dicompartimental schiff base ligands : Crystal structure of (n-n'-bis(3- methoxy or 3-ethoxysalicylidene)-1,2-diamine-2-methylpropane
The condensation of 3-methoxy or 3-ethoxy-2-hydroxybenzaldehyde and 1,2 diamine -2-methylpropane, to yield at the dianionic hexadentate Schiff base ligands H2 Ln (H2 L1 , H2 L2 respectively). The ligands have been characterised ...
Neuroprotective effects of fluorophore-labelled manganese complexes: determination of ROS production, mitochondrial membrane potential and confocal fluorescence microscopy studies in neuroblastoma cells
In this work, four manganese(II) complexes derived from the ligands H2L1-H2L4, that incorporate dansyl or tosyl fluorescent dyes, have been investigated in term of their antioxidant properties. Two of the manganese(II) ...
