Process for the preparation of methylenecyclopropane
A novel process for the production of methylenecyclopropane from 3-halogen-2-methyl-1-propene (β-methallyl halogenide) by reacting β-methyallyl halogenides with an alkali metal-bis-(trialkylsilyl)-amide, optionally in the presence of an alkali metal alcoholate and/or a corresponding alcohol. Methylenecyclopropane is obtained in a high yield, combined with a low or negligible amount of 1-methyl-cyclopropene.
