Geometric Control of C-C RE from a Pt(IV) Pincer Complex

Submitted by Adam Johnson / Harvey Mudd College on Thu, 01/04/2024 - 15:10
Description

When I saw this paper come out, I thought it would make a great teaching paper. It has synthesis, characterization, reaction mechanisms, computational chemistry and it directly impacts catalysis by a thorough examination of the reductive elimination reaction. What are the factors governing the rate of C-C RE? Can geometry (sterics) control reactivity or is it only based on the hybridization (sp2/sp3) of the carbon atom in question (electronics)?

An Exploration of Molecular Dihydrogen Complexes

Submitted by Adam Johnson / Harvey Mudd College on Mon, 11/27/2023 - 14:41
Description

I wanted my organometallic class to explore the bonding and spectroscopy of the Kubas dihydrogen complex without having to spend the time doing the entire literature discussion (which is really great and I have done it many times in the past) because I wanted to do it in only about 20-30 minutes in a 75 minute class period. Most of the questions come from the Kubas literature discussion, which I shortened. The IR and reduced mass calculations come from an LO I wrote about arene activation by Jones and Feher.

“Five” Slides About: Multiple Bonds

Submitted by Rebecca Eikey / Chestnut Hill College on Thu, 10/26/2023 - 09:15
Description

Here are 10 slides to introduce students to multiple bonds formed between transition metals and between transition metals and ligands. This can be adapted to general chemistry, as long as students have learned Lewis diagrams. This can also be extended to add more information on the nature of the multiple bonds for upper division use in inorganic and physical chemistry. 

The mechanism of Oxidative addition of Pd(0) to Si-H bonds

Submitted by Adam Johnson / Harvey Mudd College on Tue, 10/10/2023 - 18:25
Description

I saw Amanda Cook present this work (and another paper, Organometallics202241, 997) at the Organometallics Gordon Conference in summer 2023 and while I was furiously taking notes, I knew that I wanted to teach this paper. The paper elucidates the mechanism of oxidative addition of tertiary silanes to palladium zero phosphine complexes. 

Chem 165 2023

Submitted by Adam Johnson / Harvey Mudd College on Tue, 10/10/2023 - 17:56

This is a collection of LOs that I used to teach a junior-senior seminar course on organometallics during Fall 2023 at Harvey Mudd College. There were a total of 11 students in the course. Most of the students had taken one semester of both organic and physical chemistry, and about half had taken inorganic (none from me, though, as I was on sabbatical). I used the Stanley textbook hosted on this site (linked below).

Energetics and mechanisms of reductive elimination from Pt(IV) (short version)

Submitted by Adam Johnson / Harvey Mudd College on Tue, 10/10/2023 - 17:39
Description

I am moving away from teaching the Goldberg paper (still one of my favorites) and instead wanted to teach just the highlights as part of my seminar class in organometallic chemistry this fall. I created this shorter version of the activity to use in class. I did NOT have them read the paper in advance, hence the summaries in the LO itself. 

 

Stable Borepinium and Borafluorenium Heterocycles: A Reversible Thermochromic “Switch” Based on Boron–Oxygen Interactions by Robert J. Gilliard Jr.

Submitted by Niharika K Botcha / Carnegie Mellon University on Fri, 06/30/2023 - 10:27
Description

This literature discussion on the Hot Paper communication in Chemistry, A European Journal; highlights the first examples of borepinium and borfluorenium cations whose optical properties can be tuned and also the very first reported example of thermochromism in these cationic species. R. J. Gilliard, Chem. Eur. J. 2019, 25, 12512. https://doi.org/10.1002/chem.201903348

SLiThEr #48: Teaching Organometallic Chemistry to Undergraduates

Submitted by Chip Nataro / Lafayette College on Fri, 05/05/2023 - 07:49
Description

The second in a series on teaching advanced topics to undergraduates, the SLiThEr focuses on organoMetallic chemistry. While the primary framework for the discussion is my senior level course, there is plenty of great content from the live participants.

National ACS Award Winners 2023 LO Collection

Submitted by Shirley Lin / United States Naval Academy on Mon, 03/06/2023 - 11:47

This collection of learning objects was created to celebrate the National ACS Award Winners 2023 who are members of the Division of Inorganic Chemistry. The list of award winners is shown below. 

A Thousand Manipulatable Inorganic Electron-Counting Problems from Crystallography

Submitted by George Lisensky / Beloit College on Wed, 03/01/2023 - 14:40
Description

One thousand interactive organometallic and coordination complexes have been selected and prepared for practice and discovery in electron counting problems. The structures can be displayed and manipulated without requiring software installation using a web browser with JavaScript and JSmol.
