Submitted by Rachel Narehood Austin / Barnard College, Columbia University on Mon, 03/04/2024 - 08:01
Description

This LO is part of the 2024 series for national ACS award winners.  This particular LO focuses on a collaborative paper from the winner of the 2024 ACS Award for Research at an Undergraduate Institution, sponsored by Research Corporation (Rachel Narehood Austin). The award was given "for contributions to our understanding of the bioinorganic chemistry of alkane oxidation and metal binding to neurologically important metallothionein and for the development of heterogeneous catalysts."

SLiThEr #59: Inclusive leadership: Your role in creating cultures of belonging where everyone can thrive

Submitted by Matt Cranswick / Oregon State University on Wed, 02/28/2024 - 18:17

Please join us on Thursday, March 7th at 7:15 pm Eastern (4:15 pm Pacific) as Marilyn Mackiewicz (Oregon State University) presents "Inclusive leadership: Your role in creating cultures of belonging where everyone can thrive". Professor Mackiewicz is a recent awardee (2020) of the Stanley C. Israel Regional Award for Advancing Diversity in the Chemical Sciences from the ACS. Her unique story and experiences will be presented, along with how faculty can make their spaces and themselves more welcoming.

Lewis Base Stabilized Dichlorosilylene (Roesky)

Submitted by Shirley Lin / United States Naval Academy on Wed, 02/21/2024 - 15:08
Description

This literature discussion LO was created for the ACS National Award Winners 2024 collection. Dr. Herbert Roesky was the recipient of the 2024 Frederic Stanley Kipping Award in Silicon Chemistry. This LO is based on the article "Lewis Base Stabilized Dichlorosilylene" published in Angewandte Chemie 2009, 121, 5793-5796.

SLiThEr #58 (Ce): Embracing the maker culture in chemistry research and instruction

Submitted by Chip Nataro / Lafayette College on Tue, 02/13/2024 - 14:30

On Wednesday February 21 at 3 pm eastern, join BoB LeSuer (Associate Professor at SUNY - Brockport and President of IBiB) for a discussion on using a maker space for teaching chemistry. Topics include: digital fabrication of pedagogical materials (models and periodic tables); instrumentation (potentiostat and liquid dispenser); and upcycling plastics into functional materials. Of special interest to this group will be work BoB has done on making the ICE solid state model kits (see below) available to anyone.

SLiThEr #57 next Thurs, Feb 8th at 4pm EST

Submitted by Kyle Grice / DePaul University on Thu, 02/01/2024 - 12:04

Welcome to 2024!

Team SLiThEr has been hard at work arranging SLiThErs for this spring, and our first one will be in one week's time! 

The presenter will be friend of IONiC George Stanley, and the title is "What to do when your published results are questioned". We will meet at 4pm Eastern (1 pm Pacific, 2 mountain, 3 central) on Thurs Feb 8th, a week from today. 

Iridium dihydroxybipyridine complexes for hydrodeoxygenation

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

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
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

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)?
