Synthesis of bis-3,4-dialkoxythiophenes linked by am-xylene bridge

Two examples of bis 3,4-dialkoxythiophenes linked with am-xylene bridge were synthesized in yields of18% and 32% in a six step process. The formation of them-xylene bridge, key reaction of the synthesis,was carried out through Williamson, Mitsunobu andtrans-etherification reactions which were subse-...
