P2O5-MsOH mediated direct condensation of 2,2'-bis(4-benzoylphenoxy)-1,1'-binaphthyl (9) with 4-fluorobenzoic acid (10a) yielded the diaroylated monomer (11) in a moderate yield with the aid Of P2O5-MsOH. The resulting monomer (11) was allowed to react with aromatic diols 2a-c, giving the corresponding optically active aromatic polyketones (6a-c). The resulting polyketones (6a-c) have high thermal resistance and excellent solubility to organic solvents. (c) 2005 Elsevier B.V. All rights reserved.
