Mechanism of the solvatochromic reaction of a spiropyran.

Wednesday, February 4th, 2015

The journal of chemical education has many little gems providing inspiration for laboratory experiments. Jonathan Piard reports one based on the reaction below[1]; here I investigate the mechanism of this transformation.

Enantioselective epoxidation of alkenes using the Shi Fructose-based catalyst. An undergraduate experiment.

Tuesday, April 15th, 2014

The journal of chemical education can be a fertile source of ideas for undergraduate student experiments. Take this procedure for asymmetric epoxidation of an alkene.[1] When I first spotted it, I thought not only would it be interesting to do in the lab, but could be extended by incorporating some modern computational aspects as well.
