Applications of Frustrated Lewis Pairs (FLPs)

Submitted by Brad Wile / Ohio Northern University on Thu, 03/05/2020 - 11:22
Description

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. 

Inorganic Chemistry 2020

Submitted by Adam Johnson / Harvey Mudd College on Tue, 01/21/2020 - 17:35
Description

Inorganic chemistry interfaces and overlaps with the other areas of chemistry. Inorganic chemists  synthesize molecules of academic and commercial interest, measure properties such as magnetism and unpaired electron spin with sophisticated instruments, study metal ion uptake in living cells, and prepare new materials like photovoltaics. Inorganic chemistry is a diverse field, and we will only be able to touch on some of the chemistry of the 118 elements that currently reside in the periodic table.

Formal oxidation states in Ru-catalyzed water oxidation

Submitted by Margaret Scheuermann / Western Washington University on Fri, 01/17/2020 - 16:36
Description

This LO is an in-class assignment to prepare students for literature readings involving catalytic cycles in which multiple protons and electrons are transferred. Students practice assigning oxidation states to complexes with aquo, oxo, superoxo, and hydroperoxo ligands then use this information to analyze a proposed water oxidation mechanism from the literature.

Porphyrin UV-Vis

Submitted by Matthew Riehl / Minnesota State University, Mankato on Mon, 11/18/2019 - 16:30
Description

The UV-vis spectra of porphyrins are among the most recognizable spectra in the chemical literature, but the electronic transitions that lead to the observed specta are not as well known.  This presentation provides an introduction to the structure and numbering of porphyrins and the origin of the bands observed in the near UV and visible region, based on the work done by Martin Gouterman beginning in the late 1950's.    

Mechanisms of Mn-catalyzed water oxidation reactions

Submitted by Margaret Scheuermann / Western Washington University on Fri, 10/18/2019 - 19:53
Description

This LO is an in-class assignment to prepare students for literature readings involving catalytic cycles in which multiple protons and electrons are transferred. Two catalytic mechanisms, a proposed OEC mechanism and the proposed mechanism of a biomimetic OEC complexes are included. The intermediates are drawn including all charges and oxidation states, details which are sometimes omitted in the primary literature but can be helpful to students who are not accustomed to looking at multistep catalytic cycles.

Porphyrin-Based Metal-Organic Frameworks

Submitted by Amanda Bowman / Colorado College on Thu, 06/27/2019 - 15:29
Description

This literature discussion explores the physical structures, electronic structures, and spectroscopic characterization of several porphyrin-based metal-organic frameworks through discussion of “Iron and Porphyrin Metal−Organic Frameworks: Insight into Structural Diversity, Stability, and Porosity,” Fateeva et al. Cryst. Growth Des. 2015, 15, 1819-1826, http://dx.doi.org/doi:10.1021/cg501855k.
