DEF

Intermédiaire réactionnel dans lequel l'hybridation d'un atome de carbone, initialement porteur d'une double liaison (l'atome de carbone du groupe carbonyle en est un exemple typique), se trouve changée de sp² en sp³. Par exemple, l'aldol au cours de la réaction de condensation de l'acétaldéhyde (mais la plupart des intermédiaires tétraédriques ont une existence plus brève).
