Photoinduced Sulfur–Nitrogen Bond Rotation and Thermal Nitrogen Inversion in Heterocumulene OSNSO

19-Jan-2018 | Zhuang Wu; Ruijuan Feng; Jian Xu; Yan Lu; Bo Lu; Tao Yang; Gernot Frenking; Tarek Trabelsi; Joseph S. Francisco; Xia ..., Journal of the American Chemical Society, 2018

An exotic ternary S, N, O heterocumulene OSNSO in syn-syn (A) and syn-anti (B) conformations has been generated in the gas phase through flash vacuum pyrolysis of CF3S(O)NSO at 700 K. Upon visible light irradiation (570 ± 20 or 532 nm), both A and B, isolated in cryogenic matrices (N2, Ne, Ar, ...


Correction to “Tunneling Control of Chemical Reactions: The Third Reactivity Paradigm”

19-Jan-2018 | Peter R. Schreiner, Journal of the American Chemical Society, 2018

Journal of the American Chemical Society DOI: 10.1021/jacs.8b00446


Impact of Backbone Pattern and Residue Substitution on Helicity in α/β/γ-Peptides

19-Jan-2018 | Young-Hee Shin; Samuel H. Gellman, Journal of the American Chemical Society, 2018

We have evaluated the impact of changes in the chemical structure of peptidic oligomers containing α-, β-, and γ-amino acid residues (α/β/γ-peptides) on the propensities of these oligomers to adopt helical conformations in aqueous and alcoholic solutions. These studies were inspired by our ...


A Noncanonical Proximal Heme Ligand Affords an Efficient Peroxidase in a Globin Fold

19-Jan-2018 | Moritz Pott; Takahiro Hayashi; Takahiro Mori; Peer R. E. Mittl; Anthony P. Green; Donald Hilvert, Journal of the American Chemical Society, 2018

Expanding the range of genetically encoded metal coordination environments accessible within tunable protein scaffolds presents excellent opportunities for the creation of metalloenzymes with augmented properties and novel activities. Here, we demonstrate that installation of a noncanonical ...


Transmission Electron Microscopy Reveals Deposition of Metal Oxide Coatings onto Metal–Organic Frameworks

18-Jan-2018 | Michael S. Denny, Jr.; Lucas R. Parent; Joseph P. Patterson; Santosh Kumar Meena; Huy Pham; Patricia Abellan; Quenti ..., Journal of the American Chemical Society, 2018

Postsynthetic strategies for modifying metal–organic frameworks (MOFs) have proven to be an incredibly powerful approach for expanding the scope and functionality of these materials. Previously, we reported on the postsynthetic exchange (PSE) of metal ions and ligands in the University of Oslo ...


A Spectroscopic Study on the Nitrogen Electrochemical Reduction Reaction on Gold and Platinum Surfaces

18-Jan-2018 | Yao Yao; Shangqian Zhu; Haijiang Wang; Hui Li; Minhua Shao, Journal of the American Chemical Society, 2018

The electrochemical reduction of nitrogen to ammonia on Au-based catalysts showed a reasonably high Coulombic efficiency. The pathway of this promising reaction, however, is not clear partially due to the lack of information on reaction intermediates. Herein, surface-enhanced infrared absorption ...


Functional Synthetic Model for the Lanthanide-Dependent Quinoid Alcohol Dehydrogenase Active Site

18-Jan-2018 | Alex McSkimming; Thibault Cheisson; Patrick J. Carroll; Eric J. Schelter, Journal of the American Chemical Society, 2018

Journal of the American Chemical Society DOI: 10.1021/jacs.7b12318


The Effect of Water on Quinone Redox Mediators in Nonaqueous Li-O2 Batteries

18-Jan-2018 | Tao Liu; James T. Frith; Gunwoo Kim; Rachel N. Kerber; Nicolas Dubouis; Yuanlong Shao; Zigeng Liu; Pieter C. M. M. M ..., Journal of the American Chemical Society, 2018

The parasitic reactions associated with reduced oxygen species and the difficulty in achieving the high theoretical capacity have been major issues plaguing development of practical nonaqueous Li-O2 batteries. We hereby address the above issues by exploring the synergistic effect of ...


Palladium-Catalyzed Intermolecular Ditrifluoromethoxylation of Unactivated Alkenes: CF3O-Palladation Initiated by Pd(IV)

18-Jan-2018 | Chaohuang Chen; Yixin Luo; Liang Fu; Pinhong Chen; Yu Lan; Guosheng Liu, Journal of the American Chemical Society, 2018

Journal of the American Chemical Society DOI: 10.1021/jacs.7b11470


Stereodivergent Allylation of Azaaryl Acetamides and Acetates by Synergistic Iridium and Copper Catalysis

17-Jan-2018 | Xingyu Jiang; Philip Boehm; John F. Hartwig, Journal of the American Chemical Society, 2018

We report stereodivergent allylic substitution reactions of allylic esters with prochiral enolates derived from azaaryl acetamides and acetates to form products from addition of the enolates at the most substituted carbon of an allyl moiety with two catalysts, a chiral metallacyclic iridium ...
