Nitroalkene
From Wikipedia, the free encyclopedia
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.[1]
Synthesis
Nitroalkenes are synthesized by various means, notable examples include:
- Nitroaldol reactions such as the Henry Reaction:[2][3][1]
- Nitration of an alkene with nitryl iodide generated in-situ from silver nitrite and elemental iodine:[4]
- Direct nitration of alkenes with nitric oxide and an aluminum oxide catalyst in acidic conditions:[5]
- Dehydration of nitro-alcohols:[6]
Reactions
Nitroalkenes are useful intermediates for various chemical functionalities.
- Nitroalkene acting as an activated dienophile toward butadiene in an Diels-Alder cycloaddition:[8][1]
- The synthesis of pyrrole derivatives via the Barton–Zard reaction:[9]
- Pericyclic reaction of a nitroalkene yielding an indole:[10]
- Partial hydrogenation to an alkene baring a hydroxylamine functional group:[11]
- Asymmetric Stetter reaction:[13]
