Chapter 2--Stanley Organometallics

Submitted by George Stanley / Louisiana State University on Mon, 06/20/2016 - 12:57
Description

Chapter 2 from George Stanley's organometallics course, Lewis Base ligands

 

this chapter covers halides, oxygen and nitrogen donor ligands

The powerpoint slides contain answers to some of the in-class exercises, so those are behind the "faculty only" wall. I share these with students after the class, but not before.

Everyone is more than welcome to edit the materials to suit their own uses, and I would appreciate being notified of any mistakes that are found.


George Stanley Organometallics

Submitted by Adam Johnson / Harvey Mudd College on Fri, 06/10/2016 - 14:53

This is an LO for the collection of organometallics LOs by George Stanley. Adam Johnson is curating the material that was written by George.

For many years, George hosted his organometallics lecture notes, powerpoint slides, and handouts, on his personal website at LSU. He always wanted that material available to the public. Recently, they moved to a CMS and that material is no longer available. Adam is working with George to get the 2016-2017 version of his materials up on VIPEr for everyone to use.

The lecture notes are freely available to all.

chapter 1 of George Stanley's Organometallics course: Introduction, Orbitals, Electron counting

This chapter is an overview of the field, with an emphasis on electron counting

Ligand effects in titration calorimetry from the Angelici lab

Submitted by Chip Nataro / Lafayette College on Mon, 05/23/2016 - 21:08
Description

This literature discussion focuses on a paper from the Angelici lab that examines the heat of protonation of [CpʹIr(PR3)(CO)] compounds. The compounds presented in the paper provide good introductory examples for electron counting in organometallic compounds. The single carbonyl ligand in these compounds provide an excellent probe to monitor the electron richness at the metal center which is impacted by the electron donor ability of the ligands.

Mix and Match Ligand Group Orbitals and Metal Orbitals

Submitted by samuelson / Indian Institute of Science on Thu, 03/31/2016 - 00:34
Description

Students are often presented with the finished MO correlation diagrams of molecules like bis benzene chromium or ferrocene in classes and in organometallic chemistry text books. This activity helps them match the ligand group orbitals of the two benzene rings with the metal valence orbitals. Their understanding and appreciation of such diagrams is significantly enhanced when they find out how only some matches have the appropriate symmetry requirements.

Working with Catalytic Cycles

Submitted by Matt Whited / Carleton College on Mon, 09/28/2015 - 14:05
Description

Students work in groups to identify relevant steps and intermediates in 3 catalytic cycles, all the while considering bonding (and electron counting) factors.  Following assignment of these steps and intermediate species, the students consider several questions related to catalysis more broadly, particularly the role of each reagent, how to speed up or slow down specific steps, and the importance of regiospecificity in certain steps.

Iron Cross-Coupling Catalysis

Submitted by Laurel Goj Habgood / Rollins College on Wed, 09/16/2015 - 13:08
Description

In this experiment, students will synthesize and characterize an iron complex followed by completion of two series of catalytic cross-coupling reactions mimicking the methodology utilized by organometallic chemists to balance catalyst efficacy and substrate scope.  Initially the complex Fe(acac)3 [acac =  acetylacetone] is prepared.  Two sets of catalytic reactions are completed: one comparing different iron catalysts (Fe(acac)3, FeCl2, FeCl3) while the other compares substrates (4-chlorotoluene, 4-chlorobenzonitrile, 4-chlorotrifluorotoluene).

Kinetics of electrocatalytic reduction of carbon dioxide by Mn catalysts containing bulky bipyridine ligands

Submitted by Kathleen Field / WGU on Thu, 07/02/2015 - 17:23
Description

This question set has students examine the kinetics of the electrocatalytic reduction of CO2 to CO described in Sampson, D.L.; Nguygen, D., Grice, K.A.; Moore, C.E.; Rheingold, A.L.; Kubiak, C.P. Manganese Catalysts with Bulky Bipyridine Ligands for the Electrocatalytic Reduction of Carbon Dioxide:  Eliminating Dimerization and Altering Catalysis.  J. Am. Chem. Soc. 2014, 136, 5460-5471.
