Long-Range Electron Transfer Triggers Mechanistic Differences between Iron(IV)-Oxo and Iron(IV)-Imido Oxidants
Suresh Kumar,Abayomi S. Faponle,Prasenjit Barman,Anil Kumar Vardhaman,Chivukula V. Sastri,Devesh Kumar,Sam P. de Visser +6 more
TL;DR: It is shown here that iron( IV)-tosylimido complex is much more reactive with sulfides than the corresponding iron(IV)-oxo complex; however, the reverse trend is obtained for hydrogen atom abstraction reactions.
Journal ArticleDOI
Comparison of the Reactivity of Nonheme Iron(IV)–Oxo versus Iron(IV)–Imido Complexes: Which is the Better Oxidant?†
Anil Kumar Vardhaman,Prasenjit Barman,Suresh Kumar,Chivukula V. Sastri,Devesh Kumar,Sam P. de Visser +5 more
TL;DR: The iron( IV)-imido variant reacts with sulfides five times faster than iron(IV)-oxo, whereas the reverse trend is observed for hydrogen atom abstraction.
Journal ArticleDOI
Deformylation Reaction by a Nonheme Manganese(III)-Peroxo Complex via Initial Hydrogen-Atom Abstraction.
Prasenjit Barman,Pranav Upadhyay,Abayomi S. Faponle,Jitendra Kumar,Sayanta Sekhar Nag,Devesh Kumar,Chivukula V. Sastri,Sam P. de Visser +7 more
TL;DR: Metal-peroxo intermediates are key species in the catalytic cycles of nonheme metalloenzymes, but their chemical properties and reactivity patterns are still poorly understood.
Journal ArticleDOI
Keto–Enol Tautomerization Triggers an Electrophilic Aldehyde Deformylation Reaction by a Nonheme Manganese(III)-Peroxo Complex
Fabián G. Cantú Reinhard,Prasenjit Barman,Gourab Mukherjee,Jitendra Kumar,Deep Kumar,Devesh Kumar,Chivukula V. Sastri,Sam P. de Visser +7 more
TL;DR: A combined spectroscopy, kinetics and computational study on aldehyde deformylation by two side-on manganese(III)-peroxo complexes with bispidine ligands finds a novel mechanism for the reaction that is initiated by a hydrogen atom abstraction reaction, which enables a keto-enol tautomerization in the substrate.
Journal ArticleDOI
Influence of ligand architecture on oxidation reactions by high-valent nonheme manganese oxo complexes using water as a source of oxygen.
Prasenjit Barman,Anil Kumar Vardhaman,Bodo Martin,Svenja J. Wörner,Chivukula V. Sastri,Peter Comba +5 more
TL;DR: Interestingly, one of the isomers of a bispidine ligand is significantly more reactive than the other (L(1) ), while in the corresponding Fe(IV)=O based oxidation reactions the L(2) -based system was previously found to be more reactivity than the L-based catalyst.
