A brief introduction to agostic interactions and their importance to common organometallic mechanisms such as beta-hydride elimination. Examples of compounds containing these interactions are discussed and compared to familiar molecules such as diborane. Ways to characterize these interactions are also introduced.
Slides are based on the PNAS review Agostic Interactions in Transition Metal Compounds
Brookheart, Green, and Parkin Proc. Natl. Acad.Sci. 2007, 104(7), 6908-6914
Define an agostic interaction and relate it to other types of bonding.
Provide examples of how the presence of an agostic interaction can be determined experimentally and through computational methods.
This LO was developed at the VIPEr 2017 workshop at Franklin and Marshall College so it has not yet been implemented. The authors believed that implementation of this LO is best for an inorganic course that is post-organic, post-spectroscopy. It could be helpful after a discussion of 3-center 2-electron bonding and/or Lewis acidity/basicity. A literature discussion on an interesting agostic interaction with silicon was developed in conjunction with this LO and would be appropriate after discussing this five slides about LO.
