Guided Literature Discussion of “Mechanism of the Platinum(II)-Catalyzed Hydroamination of 4-Pentenylamines”

Literature Discussion

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. It includes a Reading Guide that will direct students to specific sections of the paper that were emphasized in the discussion.  This article presents a mechanistic study of hydroamination reactions catalyzed by a late transition metal complex.

Learning Goals: 

After reading and discussing this article, a student should be able to…

-  Apply the CBC electron-counting method.

-  Understand how 31P {1H} NMR can help differentiate intermediates.

-  Use information provided by Eyring plots.

-  Understand how a catalyst resting state and turnover-limiting step can be identified.

-  Understand the role of kinetics in mechanistic investigations.

-   Appreciate how proposed reaction mechanisms can be evaluated.

 

Implementation Notes: 

I am planning on assigning this LO as a graded in-class group discussion. Students will be given a copy of the article, reading guide, and discussion questions one week in advance. On the day of the discussion, students will be assigned in groups of 2-3. They will then have one lecture period to answer the questions in writing as a group. A portion of their grade (20%) is dedicated to literature discussions (4-6 over the course of the semester). The grading rubric involves 3 possible ratings for each question/answer: “excellent”, “acceptable”, or “needs work”. [This article is among the free-access ACS Editors’ Choice.]

Time Required: 
1 lecture period, with discussion materials given one week in advance

Evaluation Methods: 

Concepts covered during literature discussions will be included among exam materials.
