.

This is a list of LOs created at the TUES workshop on Organometallics at the University of Michigan in Summer 2016 (and some friends from before the workshop too). I am planning to use all of these LOs this fall in my junior/senior level course on organometallic chemistry.  I'll post comments on each LO I use.

Szymczak Learning Objects from TUES workshop

Submitted by Adam Johnson / Harvey Mudd College on Fri, 07/01/2016 - 06:46

The memebers of the Szymczak group created a collection of their learning objects from the TUES workshop at the University of Michigan in Summer 2016 to make them all easier to find.

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.

Activating H2: Mechanisms for Catalytic Hydrogenation and Hydroborylation

Submitted by Elizabeth Jensen / Aquinas College on Thu, 06/30/2016 - 22:02
Description

Based on the literature reference, this activity allows students to discover inner-sphere and outer-sphere catalytic hydrogenation mechanisms then apply their knowledge to hydroborylation. This is a guided-inquiry in-class activity that students can complete in small groups or individually with instructor support. 

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. 

Building Molecular Orbitals for a Square Pyramidal Oxorhenium(V) Complex

Submitted by M. Watzky / University of Northern Colorado on Thu, 06/30/2016 - 17:21
Description

This activity guides students into building a Molecular Orbital diagram, which focuses on metal-centered orbitals of mostly d character, for a square pyramidal complex that includes different types of ligands. Students are then asked to "fill" the resulting orbitals with metal d electrons, and examine the stability of the complex.

Design, synthesis, and carbon-heteroatom coupling reactions of organometallic nickel (IV) complexes (Sanford)

Submitted by 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.

Basics of Lanthanide-Based Photophysics

Submitted by Jacob Lutter / University of Southern Indiana on Thu, 06/30/2016 - 14:27
Description

This 5 slides about outlines the basics of lanthanide photophysics as a primer for those new to the topic.  These properties are very unique and actually very useful, which is a topic for another time.  The intricacies of what causes the Ln luminescence, its strengths and drawbacks are discussed along with how these drawbacks are addressed in molecular complexes.  Notes for the instructor are included that explain each slide.

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.
