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.

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.
