1FLO: Perhalogenated Carba-closo-dodecaborate Anions as Ligand Substituents: Applications in Gold Catalysis

Submitted by Megan Mohadjer Beromi / United States Naval Academy on Mon, 06/27/2022 - 19:58

This 1FLO focuses on the fundamentals of catalysis and the interpretation of catalytic data. The questions guide students through the definition of catalysts, turnover frequency, turnover number, and require the students to extract information from a table of catalytic data. The data set comes from the unprecedented activity of carba-closo-dodecaborate ligated gold catalysts in hydroamination reported by Lavallo and coworkers in 2013 (Lavallo, V.; Wright II, J. H.; Tham, F. S.; Quinlivan, S. Angew. Chem. Int. Ed. 2013, 52, 3172.

VIPEr Fellows 2022 Workshop Favorites

The second cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.

Discussion of "Dirhodium(II/II)/NiO Photocathode for Photoelectrocatalytic Hydrogen Evolution with Red Light" (Turro)

This Learning Object is dedicated to Prof. Claudia Turro as part of the VIPEr LGBTQIAN+ LO collection created in celebration of Pride Month (Jun) 2022. Prof. Turro was featured in the April 2022 special virtual issue Out in Inorganic Chemistry: A Celebration of LGBTQIAPN+ Inorganic Chemists (https://pubs.acs.org/doi/10.1021/acs.inorgchem.2c00729). Claudia holds a special place in my heart. I came out later in life, and she was incredibly supportive as I wrestled with my identity as a gay man.

Inorganic Chemistry

Submitted by Martin McPhail / University of West Georgia on Thu, 05/19/2022 - 15:19

The wave nature of electrons is applied to atomic structure and periodic trends. Inter and intramolecular bonding models are used to interpret the chemical and physical properties of various materials, from simplistic diatomic molecules to structurally complex molecular and ionic systems.

Catalytic Transformation of Lignin (Abu Omar)

Lignin material from plants may be transformed into useful organic materials.  This LO is part of a special VIPEr collection honoring the 2022 ACS National Award recipients in the field of inorganic chemistry. Mahdi Abu Omar was the recipient of the ACS Award in Green Chemistry for his contributions to fundamental science and technology development for catalytic lignin conversion to renewable chemicals, fuels, and materials following green chemistry and engineering principles.

Pyridylamido Hafnium and Zirconium Complexes: Synthesis, Dynamic Behavior, and Ethylene/1-octene and Propylene Polymerization Reactions (Klosin)

Submitted by Shirley Lin / United States Naval Academy on Tue, 03/08/2022 - 06:31

This literature discussion focuses on the synthesis, characterization, and polymerization behavior of non-cyclopentadienyl-based Group 4 catalysts for the polymerization of ethylene/1-octene and propylene.

This LO is part of a special VIPEr collection honoring the 2022 ACS National Award recipients in the field of inorganic chemistry. Jerzy Klosin was the recipient of the ACS Award in Industrial Chemistry for the development of versatile homogeneous catalysts for the production of a wide range of polymer-based materials on a large industrial scale.

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.

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.
