SUMMARY

The functional group R2C=N+=CR2 is definitively identified as a 2-azaallene cation. This classification aligns with the established nomenclature for similar structures, such as quaternary ammonium (R4N+), iminium (R2C=N+R2), and nitrilium (R-C≡N+-R). The discussion clarifies the naming conventions within organic chemistry, particularly for cationic species featuring multiple bonding types.

PREREQUISITES
  • Understanding of organic chemistry nomenclature
  • Familiarity with cationic species
  • Knowledge of functional groups in organic compounds
  • Basic concepts of resonance structures
NEXT STEPS
  • Research the properties and reactivity of 2-azaallenes
  • Explore the synthesis methods for cationic compounds
  • Study the implications of resonance in cationic structures
  • Investigate related functional groups and their applications in organic synthesis
USEFUL FOR

Chemistry students, organic chemists, and researchers focusing on cationic species and functional group classifications in organic compounds.

TL;DR
I don't know what these compounds are called.
I know R4N+ is a quaternary ammonium, R2C=N+R2 is an iminium, and R-C≡N+-R is a nitrilium, but what is an R2C=N+=CR2 cation called?
