This collection of learning objects was created to celebrate the National ACS Award Winners 2022 who are members of the Division of Inorganic Chemistry. The list of award winners is shown below. 

A Thousand Manipulatable Inorganic Electron-Counting Problems from Crystallography
Description

One thousand interactive organometallic and coordination complexes have been selected and prepared for practice and discovery in electron counting problems. The structures can be displayed and manipulated without requiring software installation using a web browser with JavaScript and JSmol.

Nickel-catalyzed Hydrodefluorination

Submitted by Chip Nataro / Lafayette College on Wed, 08/24/2022 - 12:29
Description

This paper describes the use of a  catalytic nickel system for the hydrodefluorination of aryl amides. While organofluorine compounds are extremely useful because of their unique properties, there are growing concerns about the impact of these compounds on the environment. Carbon-fluorine bonds are extremely strong, and so getting them to react is a significant challenge for chemists.

Hydrogenative Depolymerization of Nylons

Submitted by Chip Nataro / Lafayette College on Tue, 08/23/2022 - 13:46
Description

This paper describes work from the Milstein group in which ruthenium catalysts with pincer ligands are used to depolymerize nylons by breaking the C-N bond and hydrogenating the resulting products to amines and alcohols. Waste plastic is a serious environmental concern that needs a solution. Organometallic chemists put significant effort into finding ways to convert monomers into polymers, and now we must figure out ways to do the reverse.

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

The second cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.
