Would it be a good addition to this page to have all the many resonance structures of sydnones shown in a diagram?

Discovery[edit]
Sydnones were first prepared in Sydney, Australia in1935 by Earl & Mackney by cyclodehydration of N-Nitroso-N-phenylglycine with acetic anhydride. Later work showed that this could be applied fairly generally to the nitrosamines of N-substituted amino acids.
