Evidence of a homogeneous trinuclear Rh(I)-Cu(II)-Rh(I) catalyst for benzene C-H oxidative addition and styrene production (Gunnoe)

Submitted by John Lee / University of Tennessee Chattanooga on Wed, 03/02/2022 - 10:26

The literature discussion is based on a manuscript by Gunnoe and coworkers (ACS Catal. 2021, 11, 5688-5702. DOI: 10.1021/acscatal.1c01203). The paper presents mechanistic studies of catalytic oxidative conversion of arenes and olefins to alkenyl arenes with a focus on styrene production.

Reversible, Metal-Free Hydrogen Activation (Stephan)

Submitted by Todsapon T. / University of Evansville on Tue, 03/01/2022 - 16:35

This LO discuss various aspects of a reversible hydrogen activation by a metal-free phosphonium-borate compound.  Attentions are paid to the specific and usual reaction between highly steric phosphine and borane reactants to form a zwitterionic phosphonium borate product.  NMR spectroscopy, kinetics and thermodynamics of the hydrogen activation with the phosphonium borate product are also discussed.  The original work was published in Science by Douglas W. Stephan and co-workers.

Free Energy of Activation & Reaction Completion Times

Submitted by Joanna Webb / West Virginia Wesleyan College on Thu, 02/17/2022 - 13:39

This spreadsheet uses the Eyring equation to draw a connection between activation barriers and the timescale of a reaction. Students input a free energy of activation and can quickly see how long a reaction will take at varying temperatures. This has been particularly useful in computational sections of literature articles that investigate possible mechanistic pathways.

VIPEr nanoCHAt : NeWBiEs Spring 2022 Learning Objects

This collection accompanies the IONiC VIPEr nanoCHAt video series NeWBiEs, recorded in Spring 2022. This series is comprised of weekly conversations with two IONiC members, Wes Farrell and Shirley Lin from the US Naval Academy, as they taught a foundation-level inorganic chemistry course for the first time. The LOs discussed in the videos are included in this collection.

The course is currently designed for a student population impacted by COVID and College policies that the department offer this course every third semester. This semester I have a diverse student population in terms of developmental levels including cohort year (freshman, junior, senior), prior foundational course work (biochemistry, analytical, physical), and research experience. I have altered the assessment part of the course substantively from prior iterations and reduced topic coverage to provide flexibility.

Inorganic Chemistry 1

Submitted by Stephanie Poland / Rose-Hulman Institute of Technology on Mon, 01/10/2022 - 10:16

Course catalog description: The chemistry of non-metals. This course consists of a systematic study of the properties and reactions of the elements and their compounds based upon modern theories of the chemical bond, as well as from the viewpoint of atomic structure and the periodic law.

Efficient Hydrogenation of Ketones Catalyzed by an Iron Pincer Complex

Submitted by Todsapon T. / University of Evansville on Tue, 11/23/2021 - 11:40

This literature discussion involves various aspect of organometallic chemistry ranging from synthesis, reactions, symmetry, NMR and IR spectroscopy of organometallic compounds as well as catalysis.

Students are asked to read the article published in Angewandte Chime, and answer the questions from the worksheet. Students later discuss their answers with the entire class.
