Application of Organometallic Chemistry – Breaking the Inert C-H Bond
Description
This learning object is a literature discussion based on a paper published in Nature (Labinger, J. A.; Bercaw, J. E. Nature 2002, 417, 507-514; doi:
Metal MACiE Database
Description
As a non-bioinorganic chemist, I am always looking for resources to help me teach bioinorganic chemistry in both my sophomore-level and advanced inorganic chemistry courses. The "metalloproteome" was the subject of an article in the December 12, 2011 issue of C&E News ("Merging Metals into Proteomics: Tackling the Systematic Study of Metalloproteins"). In this article, the author mentions a new database, called Metal MACiE, of metals in metalloenzymes.
Writing assignment series related to topics discussed in organometallic chemistry - Assignment 1 Literature Summary
Description
Searching and reading the literature is an important tool in teaching organometallic chemistry. This overall project focuses on the improving students' writing skills and to begin to think critically about articles in the literature through a series of different writing assignments. This project is used in a semester long course on organometallics and reaction mechanisms. The first assignment (this LO) is a summary, the second is related to the NSF highlight, and the third is a literature critique.
Synthesis and Characterization of Ferrocene, Acetylferrocene and Ferrocenylethanol
Description
This project is designed to develop the research skills that are required to tackle projects that are larger and more complex than those encountered in first and second year chemistry courses. The lab is an integrated project-oriented laboratory including synthesis and the use of instrumental techniques such as UV-Visible and infrared, 1H-NMR and 13C-NMR spectrometry, chromatography (HPLC, TLC) and cyclic voltammetry.
Solubility and the Need for Bioinorganic Metal Ion Transport and Storage
Description
This is an in class exercise that I use to emphasize the need for metal ion transport and storage in biochemistry. Applying the Van't Hoff equation to the Ksp value at 25°C for ferric hydroxide, students calculate the iron concentration at which ferric hydroxide would begin to precipitate out in the blood. It' s an interesting problem that requires very little math beyond that used in gen chem, and the answer is in stark contrast to the amount of iron that we actually store in our bodies.
High Energy Density Materials: A laboratory and literature investigation (Christe)
Description
The synthesis of the nitrogen triiodide ammoniate shock-sensitive explosive is a simple laboratory exercise, but it does require a lengthy time for the material to dry before it is active. This activity uses that time to have students investigate some simple thermodynamics behind their explosive, as well as consult the literature on high energy density materials from the work of Karl O. Christe.
There is also a shorter version of the activity posted as an in-class activity that omits most of the literature investigation.
NMR Coin-Flip Game
Description
A simple coin-flipping game to help students understand the origin of spin/spin splitting in 1H NMR.
The Covalent Bond Classification (CBC) website
Description
The covalent bond classification (CBC) method is a way to count electrons for transition metal compounds. It classifies ligands based on their type, either L, X or Z. This is the website for all things CBC. It contains a library which list useful materials for teaching CBC including books that teach the CBC method. The site also has teaching materials that contain MLX plots for all of the transition metals. The MLX plots are charts that show various electron counts and valence for a given metal.
Five Slides About Percent Buried Volume (%Vbur)
Description
These slides present a walkthough of performing a Percent Buried Volume (%Vbur) calculation. The %Vbur is a measurement of the bulk of a ligand coordinated to a transiton metal. The calculation uses the crystal structure of a compound to determine how much space a ligand occupies. It does this by placing the metal at the center of a sphere and then calculates the volume of that sphere occupied by the ligand. Originally developed for N-heterocyclic carbene (NHC) ligands, it has also been applied to mono- and bidentate phosphines.
