Chapter 3--Stanley Organometallics

Submitted by George Stanley / Louisiana State University on Mon, 07/25/2016 - 13:15
Description

Chapter 3 from George Stanley's organometallics course, Carbonyls

 

this chapter covers bonding and structure of metal carbonyls, some descriptive chemistry, and their IR spectroscopy.

The powerpoint slides contain answers to some of the in-class exercises, so those are behind the "faculty only" wall. I shares 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.


Oxorhenium(V) Methyl, Benzyl, and Phenyl Complexes: New Mechanism for Carbonyl Insertion

Submitted by Matthew Riehl / Minnesota State University, Mankato on Thu, 06/30/2016 - 20:59
Description

The article “Synthesis and Reactivity of Oxorhenium(V) Methyl, Benzyl, and Phenyl Complexes with CO; Implications for a Unique Mechanism for Migratory Insertion,” Robbins, LK; Lilly, CP; Smeltz, JL; Boyle, PD; Ison, EA;, Organometallics 2015, 34, 3152-3158 is an interesting read for students studying reaction mechanisms of organometallic complexes.  The reading guide directs students to the sections of the paper that support the question posed in the Discussion Questions document. 

Structure matching: the $64,000 question

Submitted by Kari Stone / Lewis University on Thu, 06/30/2016 - 14:31
Description

In-class exercise that helps students learn how to use structural data and other experimental methods to assign structure. Using chemical intuition, students will rationalize the structures of metal complexes that differ by protonation states.

Electrochemical and Carbonyl Frequencies to Explain Ligand Non-Innocence in Organometallic Pincer Complexes

Submitted by Bryan Sears / Emmanuel College on Thu, 06/30/2016 - 10:52
Description

In this literature discussion, students read an Inorganic Chemistry paper (doi: 10.1021/ic503062w) about diarylamido-based PNZ pincer ligands and their Ni, Pd, and Rh complexes. Specifically, this paper uses IR and E1/2 potentials to demonstrate that the redox events occur not on the metal center but on the pincer ligands.

Ligand Design for Selectivity and Complex Stability

Submitted by Daniel Kissel / Lewis University on Wed, 06/29/2016 - 00:49
Description

This is an overview of some important principles of ligand design. Topics covered include HSAB theory, the chelate effect, the chelate ring size effect, the macrocyclic effect, the cryptate effect, and steric focus in ligand design.

Online Homework for a Foundations of Inorganic Chemistry Course

Submitted by Sabrina Sobel / Hofstra University on Mon, 06/27/2016 - 18:08
Description

The Committee on Professional Training (CPT) has restructured accreditation of Chemistry-related degrees, removing the old model of one year each of General, Analytical, Organic, and Physical Chemistry plus other relevant advanced classes as designed by the individual department. The new model (2008) requires one semester each in the five Foundation areas: Analytical, Inorganic, Organic, Biochemistry and Physical Chemistry, leaving General Chemistry as an option, with the development of advanced classes up to the individual departments.

Determining transition metal oxidation states: Recognizing bond metal-ligand types

Submitted by Brandon Quillian / Georgia Southern University on Mon, 06/27/2016 - 16:43
Description

In this in-class activity, students will determine the formal oxidation state of transition metal complexes by performing bonding type analysis of ligand−metal bonds. This in-class project is intended for those with little background in inorganic chemistry and aims to provide simple methods to calculate the formal charge of transition metals through bond-type analysis. While there are more sophisticated models already available to assign transition metal oxidation states, such as the LXZ (CBC) model, this exercise is intended for students who are coordination chemistry novices.

Coordination Compound Nomenclature Worksheet

Submitted by Elizabeth Jensen / Aquinas College on Mon, 06/27/2016 - 16:33
Description

This is a worksheet for students to complete in class to practice nomenclature of coordination compounds. It may alternatively be assigned as homework after a lesson on nomenclature. Includes examples of Ewing-Bassett system as well as Stock system.

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.

Historical overview of Evans method

Submitted by Adam Johnson / Harvey Mudd College on Wed, 06/08/2016 - 20:08
Description

This LO grew out of my interest in understanding (deeply) the machinery behind the Evans method calculations. I did these calculations as a grad student to characterize my compounds, and I teach it in both my lecture and lab. Currently I use the metal acac synthesis lab to motivate the problem.
