A nitroalkene, or nitro olefin, is a functional group combining the functionality of its constituent parts, an alkene and nitro group, while displaying its own chemical properties through alkene activation, making the functional group useful in specialty reactions such as the Michael reaction or Diels-Alder additions.

==Synthesis== Nitroalkenes are synthesized by various means, notable examples include: Nitroaldol reactions such as the Henry reaction: 375px|center Nitration of an alkene with nitryl iodide generated in-situ from silver nitrite and elemental iodine: center Direct nitration of alkenes with nitric oxide and an aluminum oxide catalyst in acidic conditions: center Direct nitration of alkenes with Clayfen (Iron(III) nitrate supported on Montmorillonite clay): center Dehydration of nitro-alcohols: center|400px In the "nitro-Hunsdiecker" reaction, nitric acid and a radical initiator convert a vinylcarboxylic acid to the corresponding nitroalkene: R2C=CCO2H + HNO3 → R2C=CNO2 + + (net)
