SLiThEr #57: What to do when your published results are questioned?

Submitted by Kyle Grice / DePaul University on Tue, 02/13/2024 - 15:19
Description

This was the 57th SLiThEr, presented by Dr. George Stanley, retired professor from LSU. It was a very interesting story and would be a valuable lesson to students about proper characterization and working with challenging and paramagnetic systems. 

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. 

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

Electron Transfer through a Photosynthetic Reaction Center

Submitted by Levi Ekanger / The College of New Jersey on Thu, 09/07/2023 - 16:23
Description

This is a computer-based activity intended for a bioinorganic chemistry course composed of upper-level undergraduate students. It is helpful for students to be familiar with concepts of electron transfer, including a surface-level introduction to Marcus theory and the inverted region, and photosynthetic charge separation before beginning this activity. However, this activity can easily be adapted to students with other levels of preparation in a bioinorganic course.

Collaborative Point Group "Escape Room" Competition

Submitted by Joya Cooley / California State University, Fullerton on Tue, 08/08/2023 - 19:29
Description

This is a digital "escape room" where students determine point groups of molecules and answer follow-up questions to determine four digits. The four digits can be used to unlock a physical lockbox which is brought to class with small prizes inside.

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
