Literature discussion for “Synthesis and characterization of a formal 21-electron cobaltocene derivative.”

Submitted by Wes Farrell / United States Naval Academy on Wed, 05/15/2024 - 14:34

This is a literature discussion regarding electron counting.  It involves several opportunities for students to use CBC to determine electron counts themselves.  Then, it demonstrates the first case of a 21-electron complex, which leads to great discussion regarding the 18-electron rule.  Throughout the discussion, students are introduced to many structural and spectrochemical analyses, some of which may be new to them.

SLiThEr #59: Inclusive leadership - Your role in creating cultures of belonging

Submitted by Chip Nataro / Lafayette College on Fri, 04/05/2024 - 15:38

Marilyn Mackiewicz (Oregon State University) is the 2020 awardee of the Stanley C. Israel Regional Award for Advancing Diversity in the Chemical Sciences from the ACS. Her unique story and experiences are presented, along with how faculty can make their spaces and themselves more welcoming.

Europium-based Contrast Agents

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Thu, 03/21/2024 - 15:34

This learning object (LO) focuses on a recent JACS paper (J. Am. Chem. Soc. 2022, 144, 23053 -23060), which explores the chemistry of EuII-based contrast agents.

Using MOF and zeolite nanoparticles to produce microporous water (Mason)

Submitted by Hilary Eppley / DePauw University on Wed, 03/13/2024 - 13:01

In fall 2023, Jarad Mason from Harvard University was awarded the ACS Award in Pure Chemistry for his contributions to the fields of phase-change materials, microporous materials, and materials chemistry.  In this literature discussion, students will examine his recent paper “Microporous water with high gas solubilities," Nature 2022, 608, 712-718 which is related to that work.

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

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

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. 

Iridium dihydroxybipyridine complexes for hydrodeoxygenation

Submitted by Adam Johnson / Harvey Mudd College on Thu, 01/04/2024 - 17:50

I regularly give an oral exam instead of a written exam in my junior and senior level organometallics seminar course. The course focuses on the primary literature, discussion of advanced topics, and asking questions. A written exam would not evaluate the students' abilities on the important skill development they learned in the class. Besides, I am better able to gauge when a student has no idea about a certain topic, or just needs a little nudge in order for them to demonstrate that they actually understand 95% of it.

Synthesis of Ti complexes supported by an ortho-terphenoxide

Submitted by Adam Johnson / Harvey Mudd College on Thu, 01/04/2024 - 16:21

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.
