Submitted by tgupta / South Dakota State University on Sat, 06/03/2017 - 11:53
Description

The set of questions in this literature discussion activity is intended to engage students in reading and interpreting scientific literature and to develop a clear and coherent understanding of agostic interactions.

Fivefold Bonding in a Cr(I) Dimer Updated and Expanded

Submitted by T Brown / SUNY Oswego on Sat, 06/03/2017 - 10:46
Description

This paper describes the synthesis and characterization of a Cr(I) dimer with a very short Cr-Cr distance. Computational studies support fivefold bonding between the chromium atoms. This paper could be used to introduce metal-metal multiple bonds and discuss the molecular orbital interactions of homonuclear diatomics including d-orbitals. More generally, it is a nice example to stimulate the discussion of what constitutes a bond and the various interpretations of bond order.

Ligand based reductive elimination from a thorium compound

Submitted by Chip Nataro / Lafayette College on Tue, 05/23/2017 - 16:52
Description

This literature discussion is based on a paper describing the ligand-based reductive elimination of a diphosphine from a thorium compound (Organometallics2017, ASAP). The thorium compound contains two bidentate NHC ligands providing an opportunity to discuss the coordination of these ligands. The ligand-based reduction is very subtle and would be challenging for students to pick up without some guidance. The compound undergoing reductive elimination also presents an excellent introduction into magnetic nonequivalence and virtual coupling.

Submitted by Sheila Smith / University of Michigan- Dearborn on Tue, 04/11/2017 - 12:11
Description

This guide, available in print, online and in an app, allows users to look up appropriate catalysts and conditions to accomplish a wide variety of reactions.

 

In-class peer review

Submitted by Chantal Stieber / Cal Poly Pomona on Fri, 03/03/2017 - 17:15
Description

This activity includes questions for students to answer to help guide them through the process of peer review. It was designed to assist students in writing peer reviews for research reports written by their classmates, but could be applied to literature articles as well.

Reactivity and Bonding of Complexes with Metal-Metal Bonds

Submitted by Chantal Stieber / Cal Poly Pomona on Wed, 03/01/2017 - 19:04
Description

This problem set was designed to be an in-class activity for students to practice applying their knowledge of metal-metal bonding (as discussed in the previous lecture) to recently published complexes in the literature. In this activity, complexes from four papers by Christine M. Thomas and coworkers are examined to give students practice in electron counting (CBC method), drawing molecular orbitals, and fundamental organometallic reactions.

Diverting Wilkinson's Catalyst: Critical Analysis of a Literature Paper

Submitted by Matt Whited / Carleton College on Tue, 02/21/2017 - 18:52
Description

This LO is a problem-set-style literature discussion that leads students through a critical analysis of an interesting but flawed paper from the recent chemical literature.  Students use the questions to help them work through the paper prior to class, providing plenty of raw material for an in-class discussion about various aspects of the work from a mechanistic organometallic perspective.  The questions help students critically analyze substrate tables, spectroscopic data, and computational results from DFT.

Description

This set of questions is intended to guide students through an excellent article by Jeff Byers and co-workers that describes the us

Guiding questions for: Redox-Controlled Polymerization of Lactide Catalyzed by Bis(imino)pyridine Iron Bis(alkoxide) Complexes

Submitted by Abby O'Connor / The College of New Jersey on Fri, 01/27/2017 - 13:37
Description

This is a literature assignment for a junior/senior level course. Guiding questions are provided to assist students with reading the article so that they see the value and importance of developing catalysts for polymerization reactions. This assignment is based upon the article
