The reverse of an
addition reaction or
transformation. In an elimination two groups (called eliminands) are lost most often from two different
centres (1/2/elimination or 1/3/elimination, etc.) with concomitant formation of an
unsaturation in the molecule (double bond, triple bond) or formation of a new ring.
If the groups are lost from a single centre (α-elimination, 1/1/elimination) the resulting
product is a
carbene or a '
carbene analogue'.
