Antibacterial Reactivity of Ag(I) Cyanoximate Complexes

Submitted by Kari Young / Centre College on Sat, 08/22/2015 - 14:09
Description

In this experiment, students will synthesize and characterize one of three Ag(I) cyanoximate complexes as potential antimicrobial agents for use in dental implants. This experiment combines simple ligand synthesis, metalation and characterization, and a biomedical application. The complexes are both air and light stable.

Synthesis of Aspirin- A Lewis Acid Approach

Submitted by Kathleen Field / WGU on Mon, 06/29/2015 - 21:29
Description

This is the procedure for a Fe(III) catalyzed synthesis of aspirin, an alternative to the traditionally sulfuric acid catalyzed synthesis of aspirin.  The prep compares and contrasts the Bronsted acid catalyzed esterification reaction with a Lewis acid iron (III) catalyzed pathway.  This can be used in different courses at different levels, but is it written for a general/intro level chemistry course.    

Photoredox Dual Catalysis for Decarboxylative Cross Coupling Reaction

Submitted by Keying Ding / Middle Tennessee State University on Mon, 06/29/2015 - 14:53
Description

In this literature discussion, students are asked to read an article describing a type of dual catalytic system in which the synergistic combination of photoredox catalysis and nickel catalysis provides a general method that would exploit naturally abundant, inexpensive organic molecules as coupling partners. This paper addresses several green chemistry principles and serves as a great literature example for teaching organometallic chemistry or green chemistry course. 

Employing 2D NMR and NOE to assign protons in an organometallic complex

Submitted by Sherzod / Northwestern University on Thu, 07/17/2014 - 20:58
Description

The following paper will be given to the students to study at home along with the questions in the attached document. Students will be allowed to discuss their answers in small groups and refine their answers, before the corresct answer is revealed.

The students will not need to see the actual spectra that are in the SI to be able to address the given questions, the spectra can be projected to the class when the answers of the student groups are discussed

A Visual Isotope Effect (a YouTube video)

Submitted by Dan O'Leary / Pomona College on Wed, 04/24/2013 - 17:46
Description

We have prepared a YouTube video demonstrating a visually accessible kinetic isotope effect in the Cr(VI) oxidation process, a reaction commonly encountered in introductory organic chemistry. The demo provides students with an opportunity to see an isotope effect and then understand how it can be used to provide mechanistic evidence for the identification of a rate-determining reaction step.

Polypropylene Stereochemistry and Identification by 13C NMR Spectroscopy

Submitted by Shirley Lin / United States Naval Academy on Mon, 07/16/2012 - 11:55
Description

These 6 slides introduce the nomenclature used to describe the stereochemistry of various polypropylenes (PPs) that can be synthesized by metallocene-catalyzed polymerizations. Although PP is the specific polymer discussed, the nomenclature applies to other alpha-olefin polymerizations.

Synthesis and Characterization of Ferrocene, Acetylferrocene and Ferrocenylethanol

Submitted by Henry Acquaye / Department of Chemistry, University of Redlands on Mon, 07/16/2012 - 10:57
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.

NMR Coin-Flip Game

Submitted by azmanam / Butler University on Fri, 06/15/2012 - 09:19
Description

A simple coin-flipping game to help students understand the origin of spin/spin splitting in 1H NMR.
