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-hydroxyphenylperfluoropropane 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
