Structural Isomer Discrimination between Cyanamides and Carbodiimides by Nitrogen Nuclear Magnetic Resonance

Abstract

The structural isomers diethylcyanamide and N,N′‐dicyclohexylcarbodiimide were studied by both proton and nitrogen NMR techniques. The structures R₂N–C≡N and R–N=C=N–R have been shown to apply to cyanamides and carbodiimides, respectively.
