VIPEr Fellows 2019 Workshop Favorites

Submitted by Barbara Reisner, James Madison University

During our first fellows workshop, the first cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.

Evaluation Methods: 

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”.

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

Evaluation Results: 



This Guided Literature Discussion was assigned as a course project, and is the result of work originated by students Christopher Lasterand Patrick Wilson.  It is based on the article “Deca-Arylsamarocene: An Unusually Inert Sm(II) Sandwich Complex” by Niels J. C. van Velzen and Sjoerd Harder in Organometallics 201837, 2263−2271. 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 study of the reactivity of bulky CpAr-Et/iPrSm complexes that is contrasted to the more well-known Cp*2Sm.

Course Level: 
Learning Goals: 

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

-      Be more familiar with the chemistry of sandwich samarocene complexes.

-      Understand how bulky ligands affect structure and reactivity in a sandwich complex.

-      Apply the CBC method to identify ligand functions and metal valence number/ligand bond number.

-       Understand how XRD bond distances can help determine a ligand charge.

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.  [This article is among the free-access ACS Editors’ Choice.]

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