Migratory Insertion Guided inquiry

Submitted by Adam Johnson / Harvey Mudd College on Mon, 04/06/2020 - 12:43
Description

The migratory insertion reaction is one of the "four" main reactions in organometallic chemistry. It involves the formation of an acyl group by insertion of a CO molecule into a metal alkyl bond. The reaction is sometimes called the carbonyl insertion reaction because the product appears to be a result of direct insertion of the CO into the metal alkyl, but that name implies a mechanistic pathway that may not be in operation.

Handling Air Sensitive Reagents and Working with a Schlenk Line (the COVID19 version)

Submitted by Lori Watson / Earlham College on Thu, 03/26/2020 - 13:18
Description

One of the features of the laboratory associated with my Inorganic chemistry course is learning to do some air sensitive chemistry using Schlenk lines (and sometimes gloveboxes).  Of course, COVID19 is keeping us out of the lab this year!  This is a collection of short web based resources (text and video) detailing begining use of a Schlenk line, something about drying and degassing solvents, and transferring liquids to a reaction flask.  It is accompanied by questions I am having students answer as part of the alternate lab I am creating in place of our usual organometallic lab experiemnt.

chromium and molybdenum arene complexes (COVID-19 version)

Description

April 2021 update: I am in the process of expanding this laboratory and have now recorded videos, linked below, on youtube. There is a video of general air sensitive reaction setup, the synthesis and isolation of the mesitylene and the N,N-diethylaniline derivatives. I also have better quality data which I will add here as well.

Ferrocene acylation - The Covid-19 Version

Submitted by Chip Nataro / Lafayette College on Sat, 03/21/2020 - 12:56
Description

This is the classic Chromatography of Ferrocene Derivatives experiment from "Synthesis and Technique in Inorganic Chemistry" 3rd Ed. (1986 pp 157-168) by R. J. Angelici.

setting up an air-sensitive reaction (video)

Submitted by Adam Johnson / Harvey Mudd College on Fri, 03/20/2020 - 20:56
Description

This is a video I made to demonstrate the basics of air-sensitive reaction setup under nitrogen flush. It is the simplest, most basic method for setting up a reaction with air/water sensitive reagents.

virtual inorganic lab experiments with data

Submitted by Adam Johnson / Harvey Mudd College on Fri, 03/20/2020 - 17:44

This collection includes new and/or updated lab experiments useful for online/distance learning. To be included in this collection, data should be provided for others to use in their new virtual laboratory courses. This collection was prepared as part of my response to the COVID-19 pandemic.

Online Seminar Talks

Submitted by Amanda Reig / Ursinus College on Thu, 03/19/2020 - 22:55
Description

In an attempt to find a substitute for our chemistry seminar program, I have found a number of YouTube videos of chemists giving seminar lectures, mostly between 2017-2020. The topics span a range of chemistry disciplines, and are all around 1 hour in length (typical seminar length).  I have not watched them, so I cannot vouch for video quality. Feel free to add additional links in the comments below if you know of or find any great talks.

We will ask students to select and watch a certain number of lectures from the list and then write and submit a one-page summary of the talk.

Chem 165 2018

Submitted by Adam Johnson / Harvey Mudd College on Sun, 06/09/2019 - 12:30

This is a collection of LOs that I used to teach a junior-senior seminar course on organometallics during Fall 2018 at Harvey Mudd College. There were a total of 9 students in the course. The Junior student (there was only one this year) was taking 2nd semester organic concurrently and had not takein inorganic (as is typical).

VIPEr Fellows 2019 Workshop Favorites

Submitted by Barbara Reisner / James Madison University on Sat, 06/08/2019 - 16:41

During our first fellows workshop, the first 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.
