Resolution of Werner complexes -- the COVID edition

Submitted by Adam Johnson / Harvey Mudd College on Fri, 02/05/2021 - 12:44

This is a classic experiment that has been revised and updated numerous times over the years. The experiment can be found in Girolami, Rauchfuss and Angelici, 3rd edition, but that edition removed some purification steps that were present in the earlier edition which has plagued generations of my students with poor resolution of the enantiomers. Marion Cass published a J. Chem. Educ. article in 2015 that included a pH determination and added back in the recrystallization step. This allowed my students to achieve higher yields and greater resolution in Spring 2020.

metal acac complexes the COVID 19 version

Submitted by Adam Johnson / Harvey Mudd College on Mon, 01/18/2021 - 16:56

For our virtual offering of inorganic chemistry laboratory at Harvey Mudd College in Spring 2021, I made some videos and collected some high quality data (IR, 1H NMR, MS, UV-Vis, mp, and X-ray diffraction) that I will make available for my students. The videos show the synthesis of Co and Mn acacs, the difference between as-prepared and recrystallized compounds, making solutions for UV-Vis and Evans method NMR, and making Evans method capillary tubes. The procedures for the synthesis of these compounds is found in Woolins (either the first or second editions). 

A cobalt hydroformylation catalyst tribute to Malcolm Green

In this paper (Llewellyn, Green and Cowley, Dalton Trans. 2006, 4164-4168) the synthesis and characterization of two cobalt compounds with an N-heterocyclic carbene ligand (IMes) are reported. the first, [Co(CO)3(IMes)Me] was prepared by the reaction of [Co(CO)3(PPh3)Me] with IMes. The second compound, [Co(CO)3(IMes)COMe] is formed by the addition of Co to the first.

Inorganic Chemistry 2020

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

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.

Descriptive Inorganic Chemistry

Submitted by Carmen Gauthier / Florida Southern College on Sun, 06/09/2019 - 09:03

Fundamental topics in inorganic chemistry will be explored, among them: atomic theory and periodicity of the elements, bonding and properties of solid state materials, main group chemistry, structure and bonding of coordination compounds, and bio-inorganic systems. The laboratory component of the course will give students experience with a various laboratory techniques used in the synthesis and characterization of inorganic compounds.

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.
