Notes:
13C—15N 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.
