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
Description

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.

Free Energy of Activation & Reaction Completion Times

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

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

Submitted by Shirley Lin / United States Naval Academy on Wed, 02/02/2022 - 18:07

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.

Efficient Hydrogenation of Ketones Catalyzed by an Iron Pincer Complex

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

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.

The Safety Net

Submitted by Amanda Reig / Ursinus College on Thu, 08/12/2021 - 11:17
Description

The Safety Net (highlighted in a BITeS post) is a great online resource for crowd-sourced standard operating procedures established by Prof. Alexander J. M. Miller (University of North Carolina at Chapel Hill) and Prof. Ian A. Tonks (University of Minnesota – Twin Cities). It primarily contains SOPs from the Miller and Tonks research groups, but they invite submissions from the chemistry community. It is a treasure trove of useful information, safety resources, and links to physical property databases.

Activation of carbon dioxide by zirconium amides

Submitted by Adam Johnson / Harvey Mudd College on Tue, 06/08/2021 - 14:48
Description

The O'Hare group has studied complexes of the permethylpentalene ligand, and recently reported the reaction of a zirconium complex of this ligand with CO2 to form the carbamate. A series of three different complexes were prepared, each with slightly different products upon reaction with CO2, illustrating subtle differences in reactivity based on either sterics or electronics. To further tangle the web, entropic and enthalpic considerations can also be considered.
