The electrochemical mediation of oxygen delignification of pulp with a manganese polyol complex
A redox cycle involving a manganese gluconate complex and oxygen in an aqueous alkaline media was investigated for its ability to delignify chemical pulp. Current applied at a cathode was used to reduce the higher oxidation states of the manganese complex. The reaction of the manganese (II) and …

Distal hydrogen-bonding effects and cofacial bimetallic salen architectures for oxygen activation chemistry
… functionalities poised over a redox active manganese salophen or salen platform. The complexes proved to be proficient catalase mimics (disproportionation of hydrogen peroxide to water and oxygen). Detailed spectroscopic, computational, and structure-function relationship studies elucidated …

De Novo Design And Engineering Of Functional Metal And Porphyrin-Binding Protein Domains
… e6 and hemin:Zn(II)-protoporphyrin IX complexes. These results imply that many sophisticated functions such as cofactor binding and electron transfer require only a very small number of residue positions in a protein sequence to be fixed.</p> <p>Net charge and hydrophobic content are …

Synthesis of Macrocyclic Polyamines and their Cu, Fe, Mn and Zn Complexes Targeting HIV (AIDS).
… against HIV by different mechanisms. The manganese complex of pyridine-fused macrocyclic polyamine (M40401) has been found to reduce HIV-1 induced apoptosis of astroglial cells. Based on these findings, seventeen new compounds were designed and synthesized, including five macrocyclic …

Studies in iridium and manganese catalysis in C-H activation and reductive transformations
… 3d transition metal catalysts, such as manganese, have gained popularity as alternatives to expensive precious metals. This trend stems from the urgent need to develop new, efficient, and sustainable green methodologies. The use of readily available metals, instead of rare noble metals, …

Synthesis of Functionalized Sustainable Polyesters via Controlled Ring-opening Polymerization of O-carboxyanhydrides
… mediated by a highly redox reactive manganese complex and a zinc-alkoxide. Mechanistic studies indicated that the ring-opening process proceeded via the Mn-mediated decarboxylation with alkoxy radical formation (Chapter 2). In addition to the polymerization, a two-step facile chemical …

Antimalarial Evaluation of Quinoline-triazoleMn(I) and Re(I) PhotoCORMs
… and their respective Mn(I) and Re(I) tricarbonyl complexes. The two ligands differ in the presence of an extended amino-propyl chain conjugated to the quinoline scaffold, which has proven to confer greater antimalarial activity. Furthermore, the complexes were evaluated for their potential as …

DFT modelling on the effect of manganese in cobalt-based FT-catalysts
… selectivity towards longer chain hydrocarbons, manganese may be added to the cobalt-based catalyst as a promoter. To this date, experimental studies have suggested that Mn exists as MnOx in the working catalyst, and it has been proposed that manganese facilitates the dissociation of CO. To …
