1FLO: Perhalogenated Carba-closo-dodecaborate Anions as Ligand Substituents: Applications in Gold Catalysis

Submitted by Megan Mohadjer Beromi / United States Naval Academy on Mon, 06/27/2022 - 19:58
Description

This 1FLO focuses on the fundamentals of catalysis and the interpretation of catalytic data. The questions guide students through the definition of catalysts, turnover frequency, turnover number, and require the students to extract information from a table of catalytic data. The data set comes from the unprecedented activity of carba-closo-dodecaborate ligated gold catalysts in hydroamination reported by Lavallo and coworkers in 2013 (Lavallo, V.; Wright II, J. H.; Tham, F. S.; Quinlivan, S. Angew. Chem. Int. Ed. 2013, 52, 3172.

VIPEr Fellows 2022 Workshop Favorites

Metal/Ligand Proton Tautomerism Facilitates Dinuclear H2 Reductive Elimination (Kuo)

Submitted by Kyle Grice / DePaul University on Tue, 06/07/2022 - 11:11
Description

This LO was developed in 2022 as part of a collection celebrating the “Out in Inorganic Chemistry: A Celebration of LGBTQIAPN+ Inorganic Chemists” Inorganic Chemistry special issue. Check out the editorial and issue here: Editorial  Special Issue

The questions below refer to the following 2020 publication by Dr. Jonathan Kuo and Dr. Karen Goldberg

Substitution Chemistry in Odd-Electron Iron Group Carbonyl Complexes (D'Acchioli)
Description

This LO brings together organometallic chemistry, electrochemistry, and computational chemistry in a complete whole, and shows how these different expertises and techniques all can add to our understanding of a rich chemical system. It might be of particular interest in a class dominated by even-electron and diamagnetic chemistry to give students an understanding of how practitioners approach odd-electron, paramagnetic systems.

Mechanistic Study of Competitive sp3-sp3 and sp2-sp3 Carbon-Carbon Reductive Elimination from a Platinum(IV) Center and the Isolation of a C-C Agostic Complex (Williams)

Submitted by Shirley Lin / United States Naval Academy on Fri, 05/20/2022 - 08:09
Description

This literature discussion focuses on a J. Am. Chem. Soc. communication that describes a series of Pt complexes that exhibit competitive reductive elimination reactions to form either an sp2-sp3 bond or an sp3-sp3 bond. One of the complexes also contains a C-C agostic interaction with the metal. The questions are written to be addressed by students in a foundation-level inorganic course.

Catalytic Transformation of Lignin (Abu Omar)

Submitted by Hilary Eppley / DePauw University on Tue, 03/15/2022 - 10:20
Description

Lignin material from plants may be transformed into useful organic materials.  This LO is part of a special VIPEr collection honoring the 2022 ACS National Award recipients in the field of inorganic chemistry. Mahdi Abu Omar was the recipient of the ACS Award in Green Chemistry for his contributions to fundamental science and technology development for catalytic lignin conversion to renewable chemicals, fuels, and materials following green chemistry and engineering principles. 

Spectroscopic, Structural, and Computational Analysis of [Re(CO)3(dippM)Br]n+ (Nataro)

Submitted by Shirley Lin / United States Naval Academy on Sat, 03/12/2022 - 06:17
Description

This literature discussion will guide students through an article that applies spectroscopic, structural, and computational analyses to a family of compounds of the type [Re(CO)3(dippM)Br]n+  (dippM = 1,1’-bis(diisopropyl)phosphino metallocene, M = Fe, n= 0 or 1; M = Co, n = 1).
