Resum
The intramolecular nature of the 1,7-O,O'-acyl migration observed during the column chromatography of the diazonium coupling products of methyl 3-acetoxy-6-hydroxy-2-methoxypentafulvene-1-carboxylate was determined by isotopic labeling and mass spectrometry. A cooperative transportation by the hydrazono group is proposed to explain this fact.
