My Notes
Categories
Short prompts for a mini review about recent applications in FLP chemistry. Trends in Chemistry also includes highlights and outstanding questions in the sidebar, which makes this an approachable review for students.

| FLPs LO | 18 KB |
Students should be able to identify some useful characteristics of a catalytic hydrogenation.
Students should be able to represent a Frustrated Lewis Pair using correct formal charges and Lewis formalisms.
Students should connect steric features of an FLP system to the chosen application.
This LO was implemented in my advanced inorganic course in spring 2020 for the first time. It updates and supplements a short lecture period in which we discussed Frustrated Lewis Pairs in historical context and recent applications. The linked review article presents some nice applications and future directions in a manner that the students found fairly approachable. We spent maybe 10 minutes discussing this in class, at the start of the next lecture period, and assessment was fairly light (did the student complete it, and participate in the discussion) - they were awarded class participation points. We built off student responses and questions for a short discussion about the utility of chiral hydrogenations and sterics in ligand design. Connections were made to the activation of inert bonds, noting the utility of a bulky (but not too bulky) ligand in stabilizing electrophilic centers. Since we haven't really dug into ligand design in great detail, this was somewhat foreshadowing for our future discussions.
Evaluation
Students are accountable to their small group to come prepared to discuss their responses. I assess this as an all or nothing class participation grade.
Students came well prepared to discuss, with hand-drawn Lewis representations. If I wanted this to be more formal, I might require a ChemDraw figure for future implementation.
