C(sp3)-F Activation through an Initial C(sp3)-H Activation Mechanism

Submitted by John Lee / University of Tennessee Chattanooga on Wed, 07/18/2012 - 16:35
Description

This paper is from a Science article from Alan Goldman’s group at Rutgers University. It was one of the literature articles that was assigned during the IONiC VIPEr Workshop in July 2012.  In conjunction with reading the article, workshop participants attended a seminar presented by Alan Goldman on this work.

Oxidative Suzuki-Type C-H Functionalization (Learning to Read a Detailed Organic Paper)

Submitted by Matt Whited / Carleton College on Tue, 07/17/2012 - 21:09
Description

This is a literature excercise I used in my upper-level organometallic course to guide students through some of the important points of a detailed organic/organometallic paper.  I have found that the first hurdles in some of these papers involve getting students to the point where they can understand (a) what specific reaction is being performed, and (b) what the role of each reagent is.  This set of questions includes a mix of material, including some things that are specifically stated in the article and some that are implied or referenced elsewhere.  I found that excercises like this one

Effects of defects on the properties of single-walled carbon nanotubes

Submitted by Sherri Lovelace-Cameron / Youngstown State University on Mon, 07/16/2012 - 21:49
Description

I teach advanced inorganic chemistry and wanted to find ways to bring in the primary literature, applications, and current research areas.  Students read the article, "Role of Defects in Single-Walled Carbon Nanotube Chemical Sensors" by Eric S. Snow, Nanoletters 2006, 6 (8) pp.

Simple synthesis of MoO2(acac)2 and evaluation of spectra

Submitted by Patricia Stan / Taylor University on Mon, 07/16/2012 - 15:23
Description

A very simple lab synthesis that allows the student to carry out a coordination reaction and then look at the NMR and IR spectra.  I use this as a first lab to introduce them to using the NMR and IR.  If students work through the spectroscopy tutorial they should be able to explain the IR and NMR spectra.

Writing assignment series related to topics discussed in organometallic chemistry - Assignment 2 Literature Highlights

Submitted by Abby O'Connor / The College of New Jersey on Mon, 07/16/2012 - 15:15
Description

Searching and reading the literature is an important tool in teaching organometallic chemistry. This overall project focuses on the improving students' writing skills and to begin to think critically about articles in the literature through a series of different writing assignments. This project is used in a semester long course on organometallics and reaction mechanisms. The first assignment (this LO) is a summary, the second is related to the NSF highlight, and the third is a literature critique.

Crystal Lattice Structures Web Site

Submitted by Chris Hamaker / Illinois State University on Mon, 07/16/2012 - 14:50
Description

A really nice site with several lattice structures indexed by several methods, and new structures are continuously being added.  I find it useful for getting images for problems sets and exams.

Distinguishing Between Metal Catalysts for Inner- and Outer-Sphere C-H Bond Functionalization

Submitted by David R. Weinberg / Colorado Mesa University on Mon, 07/16/2012 - 14:13
Description

This activity is meant to teach students about the types of homogeneous transition metal C-H bond functionalization catalysts. Before class, the students will read a short discussion of inner- and outer-sphere C-H bond functionalization catalysts. Then they will use their knowledge of transition metal oxidation states and ligands in order to assess whether a variety of catalysts react via inner- or outer-sphere pathways.

Polypropylene Stereochemistry and Identification by 13C NMR Spectroscopy

Submitted by Shirley Lin / United States Naval Academy on Mon, 07/16/2012 - 11:55
Description

These 6 slides introduce the nomenclature used to describe the stereochemistry of various polypropylenes (PPs) that can be synthesized by metallocene-catalyzed polymerizations. Although PP is the specific polymer discussed, the nomenclature applies to other alpha-olefin polymerizations.

Palladium-Catalyzed Biaryl Coupling Using PEPPSI Under Aqueous Microwave Conditions

Submitted by Gerard Rowe / University of South Carolina Aiken on Mon, 07/16/2012 - 11:53
Description

This is a lab that gives students a chance to use a catalyst to perform "green" chemistry.  Specifically, they will make one of the new generation of palladium cross-coupling catalysts called PEPPSI, which is a highly active, water soluble catalyst and use it in a Suzuki coupling reaction.  Student groups of 2 or 3 will synthesize an NHC ligand, incorporate it into a metal compound, and then perform catalysis in an aqueous microwave reaction using a variety of different reaction conditions in order to determine the optimal catalytic system.

Application of Organometallic Chemistry – Breaking the Inert C-H Bond

Submitted by John Lee / University of Tennessee Chattanooga on Mon, 07/16/2012 - 11:39
Description

This learning object is a literature discussion based on a paper published in Nature (Labinger, J. A.; Bercaw, J. E. Nature 2002, 417, 507-514; doi:10.1038/446391a) discussing the mechanisms of C-H activation by transition metal complexes. This is a topic that could be covered at the end of a section on organometallic chemistry that shows a “newer” application.
