Cyclopropanes are prepared in good yields via magnesium activation of polyhalomethyl compounds (dichlorodiphenylmethane, methyl trichloroacetate, α,α,α-trichlorotoluene, benzal chloride, benzal bromide) in the presence ofactivated olefins in DMF.

Chlorocyclopropanes and bicyclic chlorocyclopropanes are prepared in non basic conditions by electroreductive or Mg-promoted Barbier activation of PhCCl3 or Cl3CCO2Me in the presence of acyclic or cyclic α,β-unsaturated carbonyl compounds.
