Resumo:
3-Acetamidotropolone 1 reacted with p-substitutedbenzenediazonium chloride in pyridine to afford 3-acetamido-5-(4-substitutedphenylazo)tropolones 2a similar tof. Hydrolysis of compounds 2a similar tof gave 3-amino-5-(4-substitutedphenylazo)tropolanes 3a similar tof which could not be obtained directly from reactions of 3-aminotropolone with p-substitutedbenzenediazonium chloride. The structure of these new compounds 2a, 2c similar tof, 3a, 3c similar tof were confirmed from the elemental analysis and spectral data.
