Oscillating Stereocontrol: A Strategy for the Synthesis of Thermoplastic Elastomeric Polypropylene

Submitted by Shirley Lin / United States Naval Academy on Mon, 05/18/2020 - 15:25
Description

This literature discussion focuses upon the Science article by Coates and Waymouth reporting the synthesis of thermoplastic elastomeric polypropylene by an unbridged zirconocene. This article was the basis for the work done for my PhD thesis in the Waymouth group. The LO was written in May 2020 in honor of Bob Waymouth's 60th birthday. See the BITeS post announcing the LO here. 

Inorganic Active Learning Lesson Plan Design

Submitted by Meghan Porter / Indiana University on Fri, 05/15/2020 - 09:05
Description

I created this activity as a way to get the class involved in creating new, fun ways to teach course concepts (selfishly- that part is for me) and for students to review concepts prior to the final exam (for them).  Students use a template to create a 15-20 min activity that can be used in groups during class to teach a concept we have learned during the semester.  We then randomly assign the activities and students work in groups to complete them and provide feedback.

The benefits are twofold:

How to write a (good) paper

Submitted by Adam Johnson / Harvey Mudd College on Wed, 04/29/2020 - 17:50
Description

This came through my twitter feed today and I thought I would share. I'm linking to McNeil's "Resources" page which has a lot of useful info, but I am specifically talking about the "How to Write a Paper" pdf docuemnt that came from her group taking a few group meetings to discuss what made a good paper. I think this is definitely someting I will keep in mind as I work on my writing this summer!

Schlenk Line Survival guide

Submitted by Adam Johnson / Harvey Mudd College on Mon, 04/06/2020 - 14:11
Description

I feel like I've shared this resource before but I couldn't find it so maybe it will stick this time :)

This is a good resource created by "Dr. Andryj Borys, a main-group chemist, phosphorus fanatic and Schlenk line enthusiast." He is currently a postdoc in Canada, headed back to Europe in 2020 (supposedly..)

this resource describes the use of a Schlenk line in quite a bit of detail, with a variety of standard applications (cannula transfer, sealing NMR tubes).

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.

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.

Job's Method - The Covid-19 Version

Submitted by Chip Nataro / Lafayette College on Thu, 03/19/2020 - 23:03
Description

This is the classic Job's Method experiment from "Synthesis and Technique in Inorganic Chemistry" 2nd Ed. (1977 or 1986 pp 108-114) by R. J. Angelici. There are slight changes from the experiment published in the book but they just include running solutions with ethylenediamine mole fractions of 0.67 and 0.75, so details will not be provided. What is provided are a series of pictures and videos showing the experiment being performed. Also included are the raw files of the absorbance spectra in EXCEL.
