Abstract

^13^C^15^N coupling constants of a stable azomethine ylide, a 2‐aza‐1,3‐diene and an O‐tosyloxime have been measured. The large one‐bond coupling constants (21·3 and 21·6 Hz) observed for the azomethine ylide prove the dipolar structure of this compound. For the other two compounds, two‐bond coupling constants are used to derive the stereochemistry at the C,N double bond.
