A cobalt hydroformylation catalyst tribute to Malcolm Green

In this paper (Llewellyn, Green and Cowley, Dalton Trans. 2006, 4164-4168) the synthesis and characterization of two cobalt compounds with an N-heterocyclic carbene ligand (IMes) are reported. the first, [Co(CO)3(IMes)Me] was prepared by the reaction of [Co(CO)3(PPh3)Me] with IMes. The second compound, [Co(CO)3(IMes)COMe] is formed by the addition of Co to the first.

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.

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

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.

Literature Discussion for Oscillating Stereocontrol: A Strategy for the Synthesis of Thermoplastic Elastomeric Polypropylene

Submitted by Shirley Lin / United States Naval Academy on Mon, 05/18/2020 - 15:25

This literature discussion focuses upon the Science article by Coates and Waymouth reporting the synthesis of thermoplastic elastomeric polypropylene by an unbridged zirconocene. This article was the basis for the work done for my PhD thesis in the Waymouth group. The LO was written in May 2020 in honor of Bob Waymouth's 60th birthday. See the BITeS post announcing the LO here

How to write a (good) paper

Submitted by Adam Johnson / Harvey Mudd College on Wed, 04/29/2020 - 17:50

This came through my twitter feed today and I thought I would share. I'm linking to McNeil's "Resources" page which has a lot of useful info, but I am specifically talking about the "How to Write a Paper" pdf docuemnt that came from her group taking a few group meetings to discuss what made a good paper. I think this is definitely someting I will keep in mind as I work on my writing this summer!

Advanced Inorganic Chemistry

Submitted by Terrie Salupo-Bryant / Manchester University on Fri, 01/31/2020 - 16:02

Many of the topics in this course have their origins in the topics that are covered in General Chemistry but are covered in more detail.  Many of the rules learned in General Chemistry are actually the exception.  Chemical systems are much more complicated than the simple models presented in a first year course.  The course begins with the electronic structure and periodic properties of atoms followed by discussion of covalent, ionic, and metallic bonding theories and structures.  Students also apply acid-base principles to inorganic systems.  The second half of the course is dedicated to t

Inorganic Chemistry 2020

Submitted by Adam Johnson / Harvey Mudd College on Tue, 01/21/2020 - 17:35

Inorganic chemistry interfaces and overlaps with the other areas of chemistry. Inorganic chemists  synthesize molecules of academic and commercial interest, measure properties such as magnetism and unpaired electron spin with sophisticated instruments, study metal ion uptake in living cells, and prepare new materials like photovoltaics. Inorganic chemistry is a diverse field, and we will only be able to touch on some of the chemistry of the 118 elements that currently reside in the periodic table.

How to Read a Journal Article: Analyzing Author Roles and Article Components

Submitted by Catherine / East Tennessee State University on Wed, 01/08/2020 - 21:09

This literature discussion uses a recently published article on solvatochromic Mo complexes to introduce students to the different components of a research article. The activity is divied into to two parts. Before class students read the paper and focus on defining terms, investigating the "meta" data of the paper, and the different sections iof the paper. In class the students work in groups to investigate the scientific content of the paper

Mechanisms of Mn-catalyzed water oxidation reactions

Submitted by Margaret Scheuermann / Western Washington University on Fri, 10/18/2019 - 19:53

This LO is an in-class assignment to prepare students for literature readings involving catalytic cycles in which multiple protons and electrons are transferred. Two catalytic mechanisms, a proposed OEC mechanism and the proposed mechanism of a biomimetic OEC complexes are included. The intermediates are drawn including all charges and oxidation states, details which are sometimes omitted in the primary literature but can be helpful to students who are not accustomed to looking at multistep catalytic cycles.
