    Abstract

    The polymer-analogous condensation of aryl sulfoxides was proposed. The method was found to be a convenient way to synthesize thianthrene ring systems and the corresponding ladder-like polymer, heteropolyacene. Crystal structure of the thianthrenium salt revealed that the S+-C (phenyl) bond was significantly shortened upon the ring closing as a result of the increased bond order by the resonance effect.
