Methylenecyclopropane is an organic compound with the formula . It is a hydrocarbon which, as the name suggests, is derived from the addition of a methylene () substituent to a cyclopropane ring. It is a colourless, easily condensed gas that is used as a reagent in organic synthesis.
==Synthesis== Methylenecyclopropane can be synthesized via an intramolecular cyclisation reaction from methallyl chloride by treatment with a strong base such sodium amide—sodium tert-butoxide (yield 43%) or sodium bis(trimethylsilyl)amide with further treatment by sodium tert-butoxide (yield 72%). Sodium tert-butoxide is used to isomerize byproduct 1-methylcyclopropene into methylenecyclopropane. 311x311px
