Partially fluorinated aromatic polymers are of interest because they offer high thermal stability and chemical inertness in many applications. We are attempting to utilize Suzuki Polycondensation for the preparation of a partially fluorinated aromatic polymer. The two monomers coupled are bis(4-bromophenyl)-difluoromethane and bis-1,4-phenylboronic acid ester. 4,4'-Dibromobenzophenone is synthesized by Friedel Crafts acylation using bromobenzene and 4-bromobenzyl chloride. The ketone is converted to a dithiolane, which serves as a leaving group for the conversion to the difluoromethane compound. Bis-1,4-phenylboronic acid ester is synthesized from 1,4-diiodobenzne and bis(pinacolato)diboron. Progress of the work will be presented.
