Nitroalkenes are synthesized by various means, notable examples include:
* Nitroaldol reactions such as the Henry reaction:
* Nitration of an alkene with nitryl iodide generated in-situ from silver nitrite and elemental iodine:
* Direct nitration of alkenes with nitric oxide and an aluminum oxide catalyst in acidic conditions:
*Direct nitration of alkenes with Clayfen (Iron(III) nitrate supported on Montmorillonite clay):
* Dehydration of nitro-alcohols:
