Reactions of Nitrogen Substituted Carbodiimides

Attempts to synthesize N-heterocyclic substituted carbodiimides from 1,2,4-triazine imino-phosphoranes 19 and isocyanates result in the isolation of the corresponding 

The dimerization of N-t-butyl-N -dimethylaminocarbodiimide affords two isomeric dimers 21 and 22, having zwitterionic structures.
