Abstract
Abstract The polymeric materials containing thiophene units possess a number of important properties including the increased thermal stability. Thus we have developed the methods of synthesizing the diamino-, dioxy-, and tetraamino-derivatives of dibenzthiophene (DBT) and dibenzthiophendioxide (DBTD), which find their application as monomers for polymeric materials. The synthesis of these monomers was carried out with halogen-substituted DBT DBTD on Cu catalysts by ammonolysis and hydrolysis reactions and also by consecutive nitration, ammonolysis and catalytic reduction reactions.
