Abstract: This invention relates to the synthesis of bis(haloarylsulfonyl) aromatic compounds and more specifically, bis(chlorophenylsulfonyl) aromatic compounds. Bis(chlorophenylsulfonyl) aromatic compounds and particularly 4,4'-bis(4-chlorophenylsulfonyl)biphenyl are frequently used as monomers and comonomers in making high temperature polymers which possess glass transition temperatures greater than 260.degree. C. A process has been developed wherein product of high purity and minimal iron contamination is produced by reacting haloarylsulfonyl halide with an aromatic compound in the presence of an appropriate catalyst with and without solvent.
