Abstract
This invention provides a convenient and commercially adaptable process for the preparation of vinylcyclopropane derivatives in high yield. For the process an alkylating agent and activated methylene compound are reacted in the presence of a cyclic polyether compound and alkali metal compound. Water can also be present and/or the reaction may be carried out in an inert organic diluent.
