Chemistry of the Alkaline Earth Metal Enolates,toms. These compounds also become nucleophiles, if they contain an H atom in the .-position relative to their C=O or C=N bonds. This is because they can undergo tautomerization to the corresponding enol as seen in Chapter 12. They are also C,H-acidic at this position, i.e., the H atom in the .-posit

Transition Metal-Mediated Alkenylations, Arylations, and Alkynylations,be substituted by nucleophiles alone. One exception has already been discussed and that was the addition/elimination mechanism of the nucleophilic substitution. This mechanism occurs, among other substrates, with alkenes that carry a strong electron acceptor on the neighboring C atom (see Figures 10
