An elimination reaction is a reaction in which atoms or groups of atoms are removed from a molecule. There are many known elimination reactions among the various classes of molecules including but not limited to organic, inorganic and polymeric materials. Elimination reactions are the reverse process of the corresponding addition reactions. There are three common spatial arrangements for the components being eliminated among organic substrates (LG = leaving group): 1) elimination of a leaving group and a proton from the same carbon to give a reactive carbene species, 2) -elimination of a leaving group and a proton from adjacent carbons to afford an alkene, and 3) -elimination of a leaving group and a proton from carbons separated by a third carbon to give a cyclopropane (see Figure 1). The exact mechanism of each of these processes has been the focus of much research and is influenced greatly by the exact substrate...
