Abstract
The interaction of dubinidine methiodide with dilute aqueous ammonia solution and with pyridine at room temperature has been studied. In the first case the dihydrofuran ring opens, and in the second case dequaternization takes place. The dynamics of the latter process have been investigated with the aid of PMR spectroscopy, the pyrolytic transformation of dubinidine and dubinine methiodides has been studied by electron-impact mass spectrometry.
