The elusive tetrabenzylthorium compound (Bart)

Submitted by Joanne Stewart / Hope College on Thu, 03/14/2024 - 20:09
Description

This literature discussion learning object describes the isolation and structure of tetrabenzylthorium, a molecule that was synthesized many years ago but was never thoroughly characterized.

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. 

Synthesis of Ti complexes supported by an ortho-terphenoxide
Description

The Tonks group has helped to revitalize interest in early metal, especially titanium, organometallic chemistry in recent years. Often his group uses Ti complexes for multi-component coupling, increasingly with masked low-valent Ti(II) as an important intermediate. This paper is more fundamental, exploring a ligand based on ortho-terphenoxide since the meta- and para- derivatives were already known. Along the way, they report some interesting NMR and structural information, and finish with some hydroamination catalysis.

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