1,3-dipole

From Wikipedia, the free encyclopedia

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
• some ylides
  • azomethine ylide
  • nitrile ylide
  • carbonyl ylide
