Abstract
New activated bis- and tetrafluoroaromatic compounds containing the bis-phenylquinoxaline fragments, viz., methylene-bis-6(7),6"(7")-{2-(p-fluoro)phenyl-3[4-(p-fluorobenzoyl)phenyl]quinoxalines}, were prepared according to multistep procedures with the use of chloral as the starting compound. The presence of the activating carbonyl groups in the para positions with respect to two fluorine atoms opens up the possibility of the use of these monomers for the synthesis of high-molecular-weight aromatic quinoxaline-containing polyether ketones.
