What Makes a Good Nucleophile? - University of Minnesota

because of TS stabilization, not product stabilization + + + + What Makes a Good Leaving Group? 2. Polarizable. (Stabilizes transition state.) So, I is a better leaving group than F . I F good overlap, stabilization poor overlap Interesting consequence: I is both a good nucleophile and a good leaving group.

This is a GREAT TEACHING STATEMENT (not mine!). What I like about it is: 1. It is personal. 2. It is specific. 3. It is non-platitudinous. 4. Gives numerous examples. 5. Avoids sweeping generalizations and promises. 6. It is very well thought out and connected. It has a theme. Early in my education, I became a keen observer of my teachers ...

Olefin Metathesis: Catalysts and Catalysis

• Previously mentioned Grignard, Diels-Alder and Wittig reactions awarded in 1912, 1950 and 1979. • Chauvin, Grubbs and Schrock were awarded in 2005 for their work in olefin metathesis. – Preceded by decades of research prior to 2005. • Chauvin was the first to produce a viable mechanism for olefin metathesis.

ORGANOMETALLIC CHEMISTRY

Grignard reagents are synthesized through the reaction of an alkyl or aryl halide with magnesium metal. The solubility of Grignard reagents in ethers is due to the formation of a strong acid-base complex between the lone pairs of electrons on oxygen of the ether molecules and the magnesium of the Grignard reagent.
