Synthesis
Methylenecyclopropane can be synthesised via an intramolecular cyclisation reaction, using β-halo alkenes and a strong base such as sodium amide.
Reactions
Being a strained and unsaturated molecule methylenecyclopropane undergoes many reactions, especially in the presence of metal catalysts. For example, methylenecyclopropanes can be converted to cyclobutenes in the presence of a Platinum catalyst. This can be considered similar to the ring expansion seen in vinylcyclopropane rearrangements
Substituted methylenecyclopropanes can also be involved in trimethylenemethane cycloaddition reactions.
