Beautiful Chemistry

This is just a cool little website I just happened to stumble upon today while looking for something else at the RSC site. It comes from China, and it is pretty!

In-Class Review Questions for Metal Carbonyl Complexes

Submitted by Chris Goldsmith / Auburn University on Wed, 02/11/2015 - 11:24

The slides provide review questions for a senior-level treatment of the spectroscopy and reactivity of metal carbonyl complexes. These are intended to be dispersed through one to three class periods.

The first slide is a review of electron counting and the 18-electron rule.

The second slide quizzes the students on the relationship between the electron-density of the metal center and the strength of the C-O bonds in the carbonyl ligands. It is intended to be given after a discussion of how IR can be used to assess the strength of M-C and C-O bonds in the compounds.

Cobalt-Ammine complexes and theories of bonding in metals

Submitted by EGunn / Simmons College on Mon, 01/12/2015 - 12:54

This is a two-week lab in which students synthesize and then characterize three Werner cobalt complexes using IR, UV/VIS and computer calculations using Spartan. Syntheses are based on procedures from:

Angelici, R. J. Synthesis and Technique in Inorganic Chemistry. University Science Books, 1996, pp 13-17.

Borer, L.L.; Erdman, H.W.; Norris, C.; Williams, J.; Worrell, J. Synthesis of trans-Tetraamminedichlorocobalt (III) chloride, Inorganic Syntheses, Vol 31, 1997, pp 270-271.

Ligand Effects in Pd-Catalyzed Cross Coupling

Submitted by Matt Whited / Carleton College on Fri, 01/09/2015 - 14:30

This set of questions was used to promote discussion within small groups (3 to 4 students) on how changing ligand properties can have dramatic effects on the product distributions in Pd-catalyzed cross coupling reactions.  The questions are pretty difficult and not always straightforward, partly because they are derived from the primary literature and thus inherently "messy".

Zeolite Synthesis

Submitted by EGunn / Simmons College on Tue, 01/06/2015 - 16:39

This lab was part of the materials science portion of my second-year inorganic chemistry course. Students synthesize a zeolite structure and grow a chemical garden as examples of silicate chemistry.

Preparation of a Ferrofluid

Submitted by EGunn / Simmons College on Tue, 01/06/2015 - 14:12

This lab handout and supplementary materials were developed based on a publication in the Journal of Chemical Education:

Berger, P.; Adelman, N.; Beckman, K.; Campbell, D.; Ellis, A.; Lisensky, G. Preparation and Properties of an Aqueous Ferrofluid. J. Chem. Educ. 1999, 76 (7), 943-48

The Importance of the Trans Effect in the Synthesis of Novel Anti-Cancer Complexes

Submitted by Sheri Lense / University of Wisconsin Oshkosh on Mon, 01/05/2015 - 15:04

In this activity, students apply knowledge of the trans effect to the synthesis of planar Pt(II) complexes that contain cis-amine/ammine motifs.  These complexes are of interest as both potential novel chemotherapeutic Pt(II) complexes and as intermediates for promising chemotherapeutic drugs such as satraplatin.  The questions in this LO are based on recent research described in the paper “Improvements in the synthesis and understanding of the iodo-bridged intermediate en route to the Pt(IV) prodrug satraplatin,” by Timothy C. Johnstone and Stephen C.
