айырылу

An elimination is a reaction where the main feature is elimination of two ligands (atoms or groups). In a 1,2-Elimination, the ligands are lost from adjacent centers with concomitant formation of an unsaturation in the molecule. In a 1,n-Elimination (n>2), the ligands are lost from non-adjacent centers which may result in formation of a new ring. In a 1,1-Elimination, the resulting product is a carbene or "carbene analogue."
