This is a short set of slides I use to introduce aspects of coordination chemistry for my foundation level inorganic chemistry class. 

Aerobic Oxidation Catalysis via Hypervalent Iodine Intermediates

Submitted by Mario N. Cosio / Texas A&M University on Wed, 07/08/2020 - 22:31

Hypervalent iodine compounds are ubiquitous oxidants in synthetic chemistry and are often used by both organic and inorganic chemists. Typically, formation of these reagents requires stoichiometric amounts of metal-based oxidants. Methods that leverage O2 as the oxidant to
form hypervalent iodine reagents allow for O2 to be utilized as the ultimate oxidant, providing for a pathway to greener oxidation chemistry.

Demonstration of Hard-Soft Acid-Base Theory: An Ion-Exchanger for Recovery of Rare Earth Metals

Submitted by Gary L. Guillet / Georgia Southern University Armstrong Campus on Wed, 07/08/2020 - 08:19

The article from The Journal of the American Chemical Society by M. Kanatzidis et al describes a new ion-exchange material (FJSM-SnS) that shows high selectivity for rare-earth metals (REE) and very fast adsorption kinetics.  A number of techniques are used to characterize the properties of the compound that students may not be very familiar with but the article presents in an accessible way.

Pre-Modern Chemistry: A Brief World History

Submitted by Shirley Lin / United States Naval Academy on Fri, 06/19/2020 - 10:40

This Powerpoint presentation was developed to support diversity, equity and inclusion (DEI) in the chemistry classroom. One of the challenges of modern chemistry (and other modern STEM fields) is that the history discussed in general chemistry textbooks often focuses on achievements by Western scientists. While the most prominent chemists in the area of modern atomic theory were privileged, Western white men, their ideas were influenced by centuries of chemistry practiced by peoples across the globe.

A copper "Click" catalyst for the synthesis of 1,2,3-triazoles

Submitted by Chip Nataro / Lafayette College on Wed, 06/10/2020 - 11:40

This paper (Gayen, F.R.; Ali, A.A.; Bora, D.; Roy, S.; Saha, S.; Saikia, L.; Goswamee, R.L. and Saha, B. Dalton Trans2020, 49, 6578) describes the synthesis, characterization and catalytic activity of a copper complex with a ferrocene-containing Schiff base ligand. The article is relatively short but packed with information. However, many of the details that are assumed knowledge in the article make for wonderful questions some of which I hope I have captured.

Fostering a Growth Mindset: Inspiring Belief

Submitted by Anne Bentley / Lewis & Clark College on Tue, 06/09/2020 - 13:25

I developed this short class component in response to reading Saundra Yancy McGuire’s book, “Teach Students How to Learn.”  One chapter focuses on the importance of mindset, a concept developed by Carole Dweck. Students with a growth mindset believe that they can learn how to learn challenging material, while students with fixed mindsets believe that ability is innate and unchangeable.

Inorganic Active Learning Lesson Plan Design

Submitted by Meghan / Indiana University on Fri, 05/15/2020 - 09:05

I created this activity as a way to get the class involved in creating new, fun ways to teach course concepts (selfishly- that part is for me) and for students to review concepts prior to the final exam (for them).  Students use a template to create a 15-20 min activity that can be used in groups during class to teach a concept we have learned during the semester.  We then randomly assign the activities and students work in groups to complete them and provide feedback.

The benefits are twofold:

Ferrocene acylation - The Covid-19 Version

This is the classic Chromatography of Ferrocene Derivatives experiment from "Synthesis and Technique in Inorganic Chemistry" 3rd Ed. (1986 pp 157-168) by R. J. Angelici.

Job's Method - The Covid-19 Version

Submitted by Chip Nataro / Lafayette College on Thu, 03/19/2020 - 23:03

This is the classic Job's Method experiment from "Synthesis and Technique in Inorganic Chemistry" 2nd Ed. (1977 or 1986 pp 108-114) by R. J. Angelici. There are slight changes from the experiment published in the book but they just include running solutions with ethylenediamine mole fractions of 0.67 and 0.75, so details will not be provided. What is provided are a series of pictures and videos showing the experiment being performed. Also included are the raw files of the absorbance spectra in EXCEL.
