The literature discussion is based on a paper by Gagné (Organometallics 2015, 34, 2707).  In this work, the in situ generation of benzyne is examined. The benzyne coordinates to a platinum center with a tridentate (pincer) phosphine ligand and a methyl group. This provides an opportunity to discuss the characterization of compounds that have NMR active nuclei that are not 100% naturally abundant. Protonation of the benzyne compound results in the formation of toluene. Different mechanisms are considered.

This literature discussion is based on a paper describing the nucelophilic attack on a coordinated arene (Organometallics, 2015, 34,

This literature discussion is based on a paper detailing the structure and reactivity of the title compound (Organometallics, 2016, 35,

This literature discussion is based on a paper detailing catalytic transfer hydrogenation of various unsaturated organic molecules (Organometallics, 2016, 35

This literature discussion is based on a short paper describing a series of Group VI metal carbonyl compounds that have pincer ligands (Organometallics, 2016

This Guided Literature Discussion was assigned as a course project, and is the result of work originated by students Stefanie Barnett and Katelyn Yowell.  It is based on the article “Synthesis, Electrochemistry, and Reactivity of Half-Sandwich Ruthenium Complexes Bearing Metallocene-Based Bisphosphines”, Shaw, A.P.; Norton, J.R.; Bucella, D.; Sites, L.A.; Kleinbach, S.S.; Jarem, D.A.; Bocage, K.M.; Nataro, C. Organometallics 2009, 28, 3804-3814.

This literature discussion is based on one of early papers detailing the mechanism for the Monsanto acetic acid process (J. Am. Chem.

This literature discussion is based on a paper by Bill Jones and Frank Feher (J. Am. Chem. Soc., 1986, 108, 4814-4819). In this paper, they study the activation of aromatic C-H bonds by a rhodium complex. Through careful experimental design, they were able to examine isotope effects on the selectivity of the reaction. Analysis of the rate data allowed them to prepare a reaction coordinate free energy diagram. This paper also introduces the effects of C-H bond breaking in early or late transition states on the vibrational energy spacing at both ground and excited states.

A literature discussion has been developed for two courses: (i) a more basic set of questions appropriate for a sophomore level course or, possibly, a one semester upper level course that does not spend much time on organometallics, and (ii) an in-depth, in- and out-of-class set of assignments appropriate for an organometallics unit or course. Both sets of questions explore the mechanism of olefin metathesis in first- and second-generation Grubbs catalysts using a variety of spectroscopic kinetic techniques that were presented in the paper Sanford, M. S.; Love, J. A.; Grubbs, R. H. J.
