This Literature Discussion considers the synthesis of the first carbene-bismuthinidene complex by Gilliard and coworkers in 2019. This molecule serves as an illustration of different bonding models, as it can be described by multiple resonance structures invoking fully covalent, zwitterionic, and coordinate/dative bonding forms. Students analyze these resonance structures and their geometrical implications, then compare to the experimental structural evidence to come to a conclusion about which bonding model(s) best describe this molecule!

This is a literature-based end of semester project.  After a semester of introducing literature in the form of typical literature discussions, this assignment is given to small groups.  It may be easily amended or added to.  Each group is provided with a paper and accompanying questions that are similar to the literature discussions they have done over the semester.  They then must use these guiding questions to assemble a presentation to the class.  The topics chosen and the guiding questions are designed to provide students with a taste of the many areas of inorganic chemistry that are no

This literature discussion LO was created for the ACS National Award Winners 2024 collection. Dr. Holger Braunschweig was the recipient of the 2024 M. Frederick Hawthorne Award in Main Group Inorganic Chemistry. This LO is based on a figure from the article "Transition metal borylene complexes" published in Chem. Soc. Rev., 2013, 42, 3197. DOI: 10.1039/c3cs35510a.

This literature discussion was created during the 2023 IONiC VIPEr workshop at Morgan State University.  It highlights the work of Prof. Robert J. Gilliard Jr.

Guided literature reading of Angew. Chem. Int. Ed. 2021, 60, 13065-13072: Stabilization of the Elusive 9-Carbene-9-Borafluorene Monoanion.

There are three components of the assignment:

This literature discussion on the Hot Paper communication in Chemistry, A European Journal; highlights the first examples of borepinium and borfluorenium cations whose optical properties can be tuned and also the very first reported example of thermochromism in these cationic species. R.
