α-Carbon Chemistry: Enols, Enolates, and Enamines
Enamine Reactions for Carbonyl Functionalization
Description
Enamine reactions can be used to make alpha-substituted ketones and aldehydes. This chemistry is known as the Stork enamine reaction, named after Gilbert Stork. It gives students a clear example of how a carbonyl compound can be modified at the alpha carbon, which is the carbon next to the carbonyl group.

Stork enamin reaksiyonu, enamin ara ürünleri aracılığıyla α ikameli karboniller üretir.
Enaminlerde, nitrojenin yalnız çifti ile C=C bağı arasındaki konjugasyon, her ikisi de bir nükleofilik α karbon atomu barındıran enolat iyonlarına benzerliğine yol açar.
Buna rağmen, eneminler nötrdür ve net negatif yük taşıyan enolatlardan daha...
