実験手順
0.15 g (1.0 mmol) of phthalic anhydride was mixed with 0.2 to 1 equivalent of hydroxylammonium sulfate (see Table 1) and, optionally after the addition of water (see Table 1), heated to 130° C. in a sealed ampoule. The reaction times were varied for the individual mixtures in accordance with Table 1. The cooled reaction mixture was dissolved in d6-DMSO and analyzed using 1H-NMR spectroscopy. The yields are given in each case in Table 1.
