2-vinylcyclopropane derivatives has been prepared by treatment of compounds containing two acidic geminal hydrogens with base and 1,4-dibromo-(E)-2-butene.This sequence of reactions for the formation of the cyclopropane ring involves two steps: a) alkylation of a carbanion by 1,4-dibromo-2-butene, and b) intramolecular carbanion addition of the olefinic bond with concerted elimination of bromide anion from the allylic position
