Abstract

Some pyridazinium ylids used as precursors in obtaining pulmonary active drugs were studied from the point of view of intermolecular interaction nature in different solvents. The solvatochromic effect in solvents with different physicalchemical properties was used to establish the nature of the intermolecular forces acting on the pyridazinium ylid molecules in binary solutions. In the aprotic solvents only universal interactions were emphasized, while in the protic ones a supplemental hypsochromic shift of the visible electronic band proves the existence of specific interactions. The supply of different kind of interactions in pyridazinium ylid solutions was also estimated.
