A method for obtaining azomethine derivatives of pyridine and quinoline series from the corresponding carbaldehyde and amines allowing the synthesis of target products with high yields (more than 85%) is proposed. The methods of GCMS and TG/DSC-MS were used to determine the pathways of thermal destruction of the obtained derivatives, that proceeds via the cleavage of the hydrocarbon substituent from the imine fragment or the entire azomethine fragment and the formation of cationic forms of 3-phenyl-substituted pyridine and 6-substituted quinoline. Using the method of cyclic voltammetry, the electrochemical properties of the obtained compounds have been studied. It was found that electrochemical reduction/oxidation of the obtained compounds are the irreversible processes leading to fragmentation of the molecules of the obtained azomethines.
