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.

Introduction to Homogeneous Catalysis: Carbon-Carbon Bond Formation Catalyzed by a Defined Palladium Complex Wolfgang A. Herrmann, Volker P. W. Böhm, and Claus-Peter Reisinger
Students synthesize a phosphine ligand, P(o-tol)3, and with it the corresponding cyclometallated Pd(II) complex. This complex is an extremely active (pre)catalyst for C-C-bond-forming reactions (e.g. the Heck vinylation or the Grignard cross-coupling reaction). Students test the complex for activation in the catalysis of these two reactions using especially economical bromoaromatic compounds.

Synthesis of Some "Cobaloxime" Derivatives: A Demonstration of "Umpolung" in the Reactivity of an Organometallic Complex Donald L. Jameson, Joseph J. Grzybowski, Deb E. Hammels, Ronald K. Castellano, Molly E. Hoke, Kimberly Freed, Sean Basquill, Angela Mendel, and William J. Shoemaker
This article describes a four-reaction sequence for the synthesis of two organometallic "cobaloxime" derivatives. The concept of "Umpolung" or reversal of reactivity is demonstrated in the preparation of complexes. The complex Co(dmgH)2(4-t-BuPy)Et is formed by the reaction of a cobalt (I) intermediate (cobalt in the role of nucleophile) with ethyl iodide.
