Synthesis of a Series of Acetylene Terminated Oligomers: Structure Property Relationships.
Abstract
Key intermediates for the synthesis of a series of four bisacetylene aryl ether sulfones have been synthesized. The intermediates are the oligomeric bis-phenols resulting from nucleophilic aromatic substitution of 4,4'-dichlorodiphenyl sulfone with an excess of the salts of each of the following bis-phenols: 2,2-di-(4-hydroxyphenyl)perfluoropropane (IV), 4,4'-dihydroxybenzophenone (V), 4,4'-dihydroxydiphenyl ether (VI), and 4,4-dihydroxydiphenyl methane (VII). Two of the resulting oligomeric bis-phenols (those arising from IV and VI were converted to bis aryl bromides by the Ullman ether synthesis with excess amounts of m-dibromobenzene. (Author)
