Grubbs's Cross Metathesis of Eugenol with cis-2-Butene-1,4-diol To Make a Natural Product. An Organometallic Experiment for the Undergraduate Lab Douglass F. Taber and Kevin J. Frankowski
Describes the ruthenium catalyzed cross metathesis of eugenol with cis-1,4-butenediol. The experiment is an excellent example of the powerful selectivity possible with the Grubbs' catalyst, demonstrating the preference for trans over cis alkene formation and for cross metathesis over homodimerization.

Diastereoselective Synthesis of (+/-)-1,2-Diphenyl-1,2-propanediol. A Discovery-Based Grignard Reaction Suitable for a Large Organic Lab Course James A. Ciaccio, Roxana P. Bravo, Antoinette L. Drahus, John B. Biggins, Rosalyn V. Concepcion, and David Cabrera
An experiment that probes the diastereoselectivity of the reaction between a Grignard reagent and a common, inexpensive alpha-chiral ketone; introduces students to pi-facial discrimination by having them establish the stereochemical course of kinetically controlled nucleophilic addition to a carbonyl.

Grignard Reaction of an Epoxide: A Mechanistic Study James A. Ciaccio, Sabrina Volpi, Ransford Clarke
Unlike most undergraduate Grignard experiments which are performed merely for the sake of illustrating a textbook reaction, this Grignard synthesis is performed to probe the reactivity of styrene oxide. Students are required to analyze their products by TLC and NMR spectroscopy (instead of just submitting them for a grade) in order to obtain the data necessary for making mechanistic conclusions.

Carboxylic acids from halides and carbon dioxide: A facile, fast, inexpensive electrochemical synthesis Pouliquen, J.; Heintz, M.; Sock, O.; Troupel, M.
In this paper, the authors present an electrosynthesis that takes place in a one compartment cell and necessitates only a very simple constant current generator; the experiment can be run in every undergraduate organic laboratory.
