Corey–Seebach reaction
Named reaction
The Corey–Seebach reaction, or Seebach Umpolung is a name reaction of organic chemistry that allows for acylation by converting aldehydes into lithiated 1,3-dithianes. The lithiated 1,3-dithianes serves as an acyl anion equivalent, undergoing alkylation with electrophiles. The reaction is named in honor of its discoverers, Elias J. Corey and Dieter Seebach.
