Nitrosamine anions deprotonation

Dipole-Stabilization is a term coined by Beak to describe the situation that results when a carbanion is stabilized by an adjacent dipole. Such a situation arises when, for example, an amide is deprotonated a to nitrogen. The chemistry of these systems has been reviewed, - so only a few pertinent points will be made here. Firstly, metalation occurs syn to the carbonyl oxygen, and when the system is cyclic, the equatorial proton is removed selectively, and the electrophile attacks equatorially, as shown in equation (5), 24, 25 Thus, in contrast to nitrosamines, amide anions give the less stable equatorial product. 4,i25... [Pg.476]
