Summary

The constitution of hydroxyethylaminotoluquinones have been assigned by means of modern NMR-techniques. The solution equilibria constants have been determined by recording1H-NMR spectra at different temperatures. The reaction of compounds2a 1 and2c 1 with acetic anhydride leads to the corresponding acetyl derivatives with quinone skeleton. The mass spectra of2a 1 –c 1 are discussed on basis of the fragmentation pattern.
