A nucleophilic pair of electrons (either from another bond or a lone pair) heads into a new π bond as a leaving group departs. This process is called β-elimination because the bond β to the nucleophilic pair of electrons breaks. Transition metal complexes can participate in their own version of β-elimination, and metal alkyl complexes famously do so.

Additionally cyclopropanes are present in numerous biological compounds. One common method of cyclopropane synthesis is the reaction of carbenes with the double bond in alkenes or cycloalkenes. Methylene, H2C, is simplest carbene, and in general carbenes have the formula R2C.

The reaction is stereospecific since hydrogen is added in a concerted fashion from the same face of the alkene, without any opportunity for bond rotation. In the example above, we also get a stereoselective reaction since the bridgehead carbon is hindering attack of one face of the πC−C bond.
