1,3-dipole
From Wikipedia, the free encyclopedia
From top to bottom, azides, nitrones, and nitro compounds are examples of 1,3-dipoles. |
A 1,3-dipole is a type of organic compound with a three-atom pi-electron system containing 4 electrons delocalized over three atoms. They are reactants in 1,3-dipolar cycloadditions.
Known 1,3-dipoles:
- Azides
- Ozone
- Nitro compounds
- Diazo compounds
- Some oxides
- Azoxide compounds
- Carbonyl oxides (see ozonolysis)
- Nitrile oxides
- Nitrous oxide
- Nitrones
- Some imines:
- Azomethine imine
- Nitrilimines
- Carbonyl imines
