C&E News: Two's A Charm For Nickel Complex
Dr. Cundari's paper, "A Two-Coordinate Nickel Imido Complex That Effects C−H Amination," is featured in an article by Chemical & Engineering News, titled: "Two's A Charm For Nickel Complex."
A quote from the article: “This piece of work illustrates a new way to effect the catalytic synthesis of organonitrogen compounds,” says Christopher C. Cummins of Massachusetts Institute of Technology, whose group focuses on using large ligands to make low-coordinate complexes. “The two-coordinate nickel imido catalyst itself represents a breakthrough in the chemistry of nickel,” Cummins adds, “and the simplicity of the transfer reaction system renders it amenable to a high degree of mechanistic analysis.”
Dr. Borden Recipient of 2011 ACS James Flack Norris Award
The American Chemical Society awarded Dr. Wes Borden the James Flack Norris Award for Outstanding Achievement in Physical Organic Chemistry. This award pays tribute to outstanding contributions to the field of physical organic chemistry.
Publication Chosen as Hot Paper: Catalytic C-H Amination with Unactivated Amines through Copper(II) Amides
Dr. Cundari recently published "Catalytic C-H Amination with Unactivated Amines through Copper(II) Amides" in "Angewandte Chemie International Edition." This paper was chosen as a Hot Paper, a paper chosen by the editors for its importance.
A quote from the abstract:
Two equivalents of the three-coordinate copper(II) amide [(Cl2NN)Cu]-NHAd participate in stoichiometric C
H amination by a H-atom abstraction/radical capture sequence. This active species may be generated through a copper(II) tert-butoxide intermediate to allow for the unprecedented catalytic amination of sp3-CH bonds with unactivated alkylamines. This method greatly expands the range of amines for catalytic CH amination since most protocols require N-based electron-withdrawing groups.

New Publication: Towards More Relaxed Conditions for a Gamma-ray Laser:
Methods to Realize Induced Transparency for Nuclear Resonant Gamma Radiation
Dr. Rostovtsev recently published "Towards more relaxed conditions for a gamma-ray laser: Methods to realize induced transparency for nuclear resonant gamma radiation" in "Laser & Photonics Review"
A quote from the abstract:
The ability to determine the structure of matter in three dimensions has profoundly advanced our understanding of nature. Traditionally, the most widely used schemes for three-dimensional (3D) structure determination of an object are implemented by acquiring multiple measurements over various sample orientations, as in the case of crystallography and tomography1, 2, or by scanning a series of thin sections through the sample, as in confocal microscopy3. Here we present a 3D imaging modality, termed ankylography (derived from the Greek words ankylos meaning ‘curved’ and graphein meaning ‘writing’), which under certain circumstances enables complete 3D structure determination from a single exposure using a monochromatic incident beam.

New Publication: Three-Dimensional Structure Determination from a Single View
Dr. Du recently published "Three-dimensional Structure Determination from a Single View" in the "Nature, International Weekly Journal of Science."
A quote from the abstract:
We suggest and demonstrate that the proper use of these “bright” and “dark” exciton states with distinctively different recombination times may turn the situation around: the use of quantum coherence and multiphoton schemes of excitation potentially not only allow one to efficiently manipulate the dark states, but can also create conditions for efficient light generation in different frequency regions, produce “slow” or “fast” light, implement quantum light storage, and media with a negative refractive index.

New Publication: Computational Study of Methane C-H Activation by First-Row Late Transition Metal LnM=E (M: Fe, Co, Ni) Complexes
Aaron Pierpont and Dr. Tom Cundari recently published their Computational Study of Methane C-H Activation by First-Row Late Transition Metal LnM=E (M: Fe, Co, Ni) Complexes in the ACS journal: Inorganic Chemistry. The article is featured as the cover article for the journal.
A quote from the abstract:
Methane functionalization via LnM═E active species (Ln = β-diketiminate, dihydrophosphinoethane; M = Fe−Ni, E = NCF3, NCH3, O) through a hydrogen atom abstraction (HAA)/radical rebound (RR) mechanism is calculated to be thermodynamically and kinetically feasible. The enthalpies of each reaction decrease in the order Fe > Co > Ni and with the proximity of CF3 supporting ligand substituents (“fluorination”) to the metal center.

"Toward Greener Carbon Capture Technologies: A Pharmacophore-Based Approach to Predict CO2 Binding Sites in Proteins"
by Drs. Drummond, Wilson, and Cundari
Dr. Michael Drummond, along with Drs. Angela Wilson and Thomas Cundari, published a new article on December 30, 2009 titled: Toward Greener Carbon Capture Technologies: A Pharmacophore-Based Approach to Predict CO2 Binding Sites in Proteins". This publication is featured in the ACS News Service Weekly PressPac: February 03, 2010, which states: "Carbon dioxide from industrial smokestacks could be captured with eco-friendly proteins developed with a technique long used to discover new medicines."
A quote from the abstract:
"Successful sequestration of emitted carbon dioxide is a crucial ingredient in addressing rising atmospheric CO2 concentrations, but current CO2 capture technologies are often corrosive and can generate hazardous waste. Inspiration for more environmentally friendly sequestration is sought in Nature by searching for common patterns by which proteins bind CO2. Specifically, three-dimensional functional group patterns responsible for binding CO2 are extracted from the few protein-CO2 complexes that have been characterized by X-ray Crystallography."
