text: Yo, listen up, I got some knowledge to drop,
  About 2-Alkoxycarbonylazolium N-aminides, a hip-hop,
  These species got potential, they ain't no joke,
  They act like 1,4-dipole equivalents, ready to provoke.
  
  When they mix with heterocumulenes, straight up,
  Iso(thio)cyanates and carbodiimides, yup,
  Reactions go down, forming heterobetaines,
  With that imidazo[2,1-f][1,2,4]triazinium system in their veins.
  
  But hold up, there's more, don't you know,
  These N-aminides got another flow,
  They can act as 1,3-dipoles, switchin' gears,
  When they meet isocyanates, it's a whole new frontier.
  
  Cycloadducts be formed, dependin' on the group,
  Alkoxycarbonyl's position, it'll make you swoop,
  Either a reversion process or a ring expansion,
  To the more stable heterobetaine system, that's the intention.
