NMR-spektroskopische und massenspektrometrische Untersuchung der Struktur und L�sungsgleichgewichte von Hydroxyethylaminotoluchinonen
摘要:
The constitution of hydroxyethylaminotoluquinones have been assigned by means of modern NMR-techniques. The solution equilibria constants have been determined by recording H-1-NMR spectra at different temperatures. The reaction of compounds 2a1 and 2c1 with acetic anhydride leads to the corresponding acetyl derivatives with quinone skeleton. The mass spectra of 2a1-c1 are discussed on basis of the fragmentation pattern.
