Electrochemical Oxidation of Aliphatic Carboxylates: Kinetics, Thermodynamics, Mechanism, and the Role of Hydrogen Bonding
Autor: Dr. Marwa K. Abdel Latif, Dr. Jared N. Spencer, Dr. Bryce E. Kidd, Dr. Louis A. Madsen, Dr. James M. Tanko
Publikováno v: ChemElectroChem, Vol 11, Iss 11, Pp n/a-n/a (2024)
Abstract The oxidation of tetra‐n‐butylammonium acetate, propionate, and pivalate was studied in rigorously anhydrous acetonitrile by conventional linear sweep and convolution voltammetry (LSV and ConV, respectively). The results suggest oxidatio

Insight into Hydrogen Abstractions by Nitrate Radical: Structural, Solvent Effects, and Evidence for a Polar Transition State
Autor: Mark Paradzinsky, Diego Troya, James M. Tanko
Publikováno v: The Journal of Physical Chemistry A. 125:5471-5480
The role of a polarized transition state and solvent effects on nitrate radical reactions was examined with a previously under-reported class of substrates, ethers, for their atmospheric implications. Absolute rate constants for hydrogen abstraction

Interplay between Structure and Mechanism in Reductive Dissociative Electron Transfers to α,β ‐Epoxyketones
Autor: James M. Tanko, Michelle L. Grimm, Jared N. Spencer
Publikováno v: ChemPlusChem. 85:2387-2396
The electrochemical reduction of several α,β -epoxyketones was studied using cyclic (linear sweep) voltammetry, convolution voltammetry, and homogeneous redox catalysis. The results were reconciled to pertinent theories of electron transfer. α,β

Stereoelectronic and Resonance Effects on the Rate of Ring Opening of N-Cyclopropyl-Based Single Electron Transfer Probes
Autor: James M. Tanko, Michelle L. Grimm, N. Kamrudin Suleman, Jared N. Spencer, Amber N. Hancock, Neal Castagnoli, Rozhin Rowshanpour, Travis C Dudding
Publikováno v: Journal of the American Chemical Society. 142:2640-2652
N-Cyclopropyl-N-methylaniline (5) is a poor probe for single electron transfer (SET) because the corresponding radical cation undergoes cyclopropane ring opening with a rate constant of only 4.1 × 104 s-1, too slow to compete with other processes su

Autor: James M. Tanko, Paul A. Deck, Marwa Abdel Latif, Neal Castagnoli, Akiko Nakamura
Publikováno v: Chemistry – A European Journal. 26:823-829
Mechanistic studies with 5-ethyl-3-methyllumiflavinium (Fl+ ) perchlorate, a biomimetic model for flavoenzyme monoamine oxidase B (MAO-B) catalysis, and the tertiary, allyl amine 1-methyl-4-(1-methyl-1 H-pyrrol-2-yl)-1,2,3,6-tetrahydropyridine (MMTP)

Improving the Efficiency of the Mn2+/3+ Couple in Quantum Dot Solar Cells: The Role of Spin Crossover
Autor: Rachael Langlois, James M. Tanko, Shaunak M. Shaikh, Jonathan Roof, Amanda J. Morris, Matthew C. Kessinger
Publikováno v: The Journal of Physical Chemistry C. 122:14135-14149
In this study, we present the synthesis of a family of first-row transition metal redox mediators based on the bis[hydrotris(pyrazolyl)]borate manganese(II/III) (MnTp2) redox couple. Using cyclic voltammetry, the electrochemical properties and charac

Radical additions of acyclic and cyclic ethers to alkenes via an allyl transfer reaction involving phthalimido-N-oxyl radical
Autor: Shradha Patil, James M. Tanko
Publikováno v: Tetrahedron. 72:7849-7858
Direct functionalization of rudimentary and cheap starting materials to yield complex value added products is of great interest to synthetic chemists. Particularly, direct functionalization of cheap commodity molecules that have been traditionally co

Publikováno v: Polymer. 191:122258
Poly (ethylene 2,2′-bifuran-5,5′dicarboxylate) (PEBF) is a new biosourced polyester recently reported to have significant enhancement of oxygen barrier properties and glass transition temperature when compared to poly (ethylene terephthalate). We
