In-Class Review Questions for Metal Carbonyl Complexes

Submitted by Chris Goldsmith / Auburn University on Wed, 02/11/2015 - 11:24
Description

The slides provide review questions for a senior-level treatment of the spectroscopy and reactivity of metal carbonyl complexes. These are intended to be dispersed through one to three class periods.

The first slide is a review of electron counting and the 18-electron rule.

The second slide quizzes the students on the relationship between the electron-density of the metal center and the strength of the C-O bonds in the carbonyl ligands. It is intended to be given after a discussion of how IR can be used to assess the strength of M-C and C-O bonds in the compounds.

Organometallics course F 2014

Submitted by Adam Johnson / Harvey Mudd College on Fri, 01/23/2015 - 16:54

This is a collection of LOs that I used to teach a junior-senior seminar course on organometallics during Fall 2014 at Harvey Mudd College.

Ligand Effects in Pd-Catalyzed Cross Coupling

Submitted by Matt Whited / Carleton College on Fri, 01/09/2015 - 14:30
Description

This set of questions was used to promote discussion within small groups (3 to 4 students) on how changing ligand properties can have dramatic effects on the product distributions in Pd-catalyzed cross coupling reactions.  The questions are pretty difficult and not always straightforward, partly because they are derived from the primary literature and thus inherently "messy".

Learning from UCLA

Submitted by Sheri Lense / University of Wisconsin Oshkosh on Sat, 09/20/2014 - 19:47
Description

This learning object is designed to spark discussion and educate students taking an inorganic chemistry course about laboratory safety.  It uses the article "Learning from UCLA" by Jyllian N. Kemsley (Chemical & Engineering News (2009), Vol. 87 Issue 31, pp.

A Tale of Two Structures

Submitted by Chip Nataro / Lafayette College on Tue, 08/12/2014 - 10:32
Description

In this activity, students will compare and contrast two closely related structures, [Pd(dcpf)PR3]2+ (dcpf = 1,1'-bis(dicyclohexylphosphino)ferrocene; R = Me or Ph). They will be required to obtain the cif files from the supporting information of a paper. They will then make a variety of measurments in the two stuctures. These measurements can be made using a variety of different freely available programs. Instructions are provided for Mercury 3.3 and Olex2. Finally, students will be required to provide a rationale for the differences in the two structures.

Employing 2D NMR and NOE to assign protons in an organometallic complex

Submitted by Sherzod / Northwestern University on Thu, 07/17/2014 - 20:58
Description

The following paper will be given to the students to study at home along with the questions in the attached document. Students will be allowed to discuss their answers in small groups and refine their answers, before the corresct answer is revealed.

The students will not need to see the actual spectra that are in the SI to be able to address the given questions, the spectra can be projected to the class when the answers of the student groups are discussed

Dissecting Catalysts for Artificial Photosynthesis

Submitted by Anne Bentley / Lewis & Clark College on Mon, 07/07/2014 - 13:57
Description

Anne asked the students in her junior/senior inorganic course to develop their own literature discussion learning objects and lead the rest of the class in a discussion of their article.  Each student chose one article from a list of suggestions provided.  Student Hayley Johnston chose this article describing a Mn-containing catalyst for carbon dioxide reduction (Jonathan M. Smieja, Matthew D. Sampson, Kyle A. Grice, Eric E. Benson, Jesse D. Froehlich, and Clifford P.

Five Slides About Concurrent Tandem Catalysis

Submitted by Shirley Lin / United States Naval Academy on Thu, 07/03/2014 - 12:54
Description

This set of slides is adapted from a presentation given at the ACS National Meeting in New Orleans Spring 2013 in the symposium "Undergraduate Research at the Frontiers of Inorganic Chemistry" organized by members of the VIPEr leadership council. The slides are from the introduction to the presentation that takes the audience through how catalytic cycles are depicted and then to the concept of concurrent tandem catalysis (CTC). At the end, there is a slide with references that gives an example of how CTC can be applied to aryl halide substrates to form new C-C and C-H bonds.

Properties of olefin complexes: Pt(II) vs Au(III)

Submitted by Margaret Scheuermann / Western Washington University on Sat, 06/21/2014 - 22:01
Description

This is a literature discussion based on a paper titled “Generation and Structural Characterization of a Gold(III) Alkene Complex” (Angew. Chem. Int. Ed. 2013, 52, 1660 - DOI 10.1002/anie.201209140) that reports the first crystallographically characterized Au(III) alkene complex, [(cod)AuMe2] [BArF]. The synthesis and characterization of [(cod)AuMe2] [BArF] are presented. The structural properties are compared to those of the isoelectronic species (cod)PtMe2, and to free cod.
