Kinetic and Mechanistic Aspects of Atom Transfer Radical Addition (ATRA) Catalyzed by Copper Complexes

Submitted by Abby O'Connor / The College of New Jersey on Thu, 12/15/2016 - 17:28
Description

Reading and understanding a journal article is a critical skill to obtain as a student. After college, many students will pursue careers in which learning occurs exclusively from the literature. Students  will read a full paper from the journal Inorganic Chemistry and answer guiding questions pertaining to the article. There will be an in class discussion about the article to introduce which is used to introduce the topic of catalysis. This assignment breaks down the article through a series of questions that helps students to navigate a journal article.

Introduction to Atom Economy and the Hydroamination Reaction

Submitted by Eugene Chong / University of Michigan on Fri, 07/01/2016 - 02:04
Description

This 5 slides about introduces the term "atom economy" as a means for undergraduates to start thinking about the efficiency of synthetic reactions. While this term may not be the best measure of the overall process of a reaction (as it ignores other factors such as solvents and materials used in purification), it provides a nice introduction to a concept on green chemistry. An example of an atom economic reaction, hydroamination, is briefly highlighted as it is an important ongoing research area. Notes for the instructor are included in the slides.

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. 

Literature Discussion of “Design, synthesis, and carbon-heteroatom coupling reactions of organometallic nickel (IV) complexes.”

Submitted by Dr. Daniel Kissel / Lewis University on Thu, 06/30/2016 - 17:05
Description

This literature discussion is designed for upper-level inorganic chemistry students. The article explores the motivations, design, and characterization of novel nickel(II) and nickel(IV) complexes for carbon-heteroatom bond forming reactions. Students can apply and integrate their knowledge of organic chemistry mechanisms, organometallic chemistry, and techniques for characterizing metal-ligand compounds that include NMR and CV.

Zones of Catalysis: Only the Metal? A literature Discussion of Outer-Sphere Hydroboration

Submitted by Santiago Toledo / St. Edward's University on Thu, 06/30/2016 - 14:51
Description

This literature activity is designed to introduce students to the concept of outer-sphere hydroboration catalytic reactions. It can be used after hydrogenation and hydroboration reactions have been introduced in class (typically covered in organic chemistry). Additionally, this activity allows students to apply their understanding of redox chemistry, acid base chemistry, and physical techniques to characterize products and elucidate reactions mechanisms.

Ligand Design for Selectivity and Complex Stability

Submitted by Dr. 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.

A Guided-Inquiry Approach to Building a Catalytic Cycle

Submitted by M. Watzky / University of Northern Colorado on Mon, 06/27/2016 - 19:00
Description

This activity introduces students to fundamental types of organometallic reactions, and directs them to examine how each of these reactions affects the total electron count for the organometallic complex and the oxidation state of the central metal.  Students are then directed to use these reactions to build a sequence of steps for a catalytic cycle.

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.

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.

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.
