Redox-switch polymerization catalysis

Submitted by Chip Nataro / Lafayette College on Tue, 03/26/2019 - 13:49
Description

This is the full literature discussion based on a communicaiton (J. Am. Chem. Soc. 2011133, 9278). This paper describes a redox-switch yttrium catalyst that is an active catalyst for the polymerization of L-lactide in the reduced form and inactive in the oxidized form. The catalyst contains a ferrocene-based ligand that serves as the redox active site in the catalyst. This full literature discussion is an extension of the one figure literature discussion that is listed below.

1FLO: Redox-switch polymerization catalysis

Submitted by Chip Nataro / Lafayette College on Fri, 03/22/2019 - 16:11
Description

This is what I hope will be a new classification of learning object called a one figure learning object (1FLO). The purpose is to take a single figure from a paper and present students with a series of questions related to interpreting the figure. This literature discussion is based on a paper (J. Am. Chem. Soc. 2011, 133, 9278) from Paula Diaconescu's lab in which a yttrium polymerization catalyst with a ferrocene-based ligand can effectively be rendered active or inactive depeneding on the valence state of the ligand.

Advanced ChemDraw (2019 Community Challenge #2)

Submitted by Chantal Stieber / Cal Poly Pomona on Tue, 02/12/2019 - 12:12
Description

This in-class activity was designed for a Chemical Communications course with second-year students. It is the second part of a two-week segment in which students learn how to use ChemDraw (or similar drawing software to create digital drawings of molecules).

5-ish Slides About Bridging Hydrides and the [Cr(CO)5HCr(CO)5] anion

Submitted by Kyle Grice / DePaul University on Thu, 01/31/2019 - 13:52
Description

This set of slides was made for my Organometallics class based on questions about bridging hydrides and specifically the chromium molecule. I decided to make these slides to answer the questions, and do a DFT calc to show the MO's involved in bonding of the hydride.

Description

This Guided Literature Discussion was assigned as a course project, and is the result of work originated by students Jana Forster and Kristofer Reiser.  It is based on the article “Mechanism of the Platinum(II)-Catalyzed Hydroamination of 4-Pentenylamines” by Christopher F. Bender, Timothy J. Brown, and Ross A. Widenhoefer in Organometallics 2016 35 (2), 113-125.

Bonding and MO Theory in Flavodiiron Nitrosyl Model Complexes - Advanced Level

Submitted by Cassie Lilly / NCSU on Sat, 06/23/2018 - 11:20
Description

The activity is designed to be a literature discussion based on Nicolai Lehnert's Inorganic Chemistry paper, Mechanism of N-N Bond Formation by Transition Metal-Nitrosyl Complexes: Modeling Flavodiiron Nitric Oxide Reductases.  The discussion questions are designed for an advanced level inorganic course. 

 

Characterization and Investigation of a Binuclear Manganese(III)-Peroxo Metastable Intermediate

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 05/17/2018 - 16:15
Description

In this literature assignment, students are asked to read an article from the primary literature on a binuclear manganese-peroxo complex that is similar to species proposed to be involved in photosynthetic water splitting and DNA biosynthesis. The assignment contains 25 questions that are intended to guide students through the article and help them extract important information about the work. The completed questions are then used as the basis for an in-class discussion of model complexes, which leads to a more advanced discussion on the topic.
