Abstract

A simple and efficient approach is developed for the synthesis of substituted 2, 2′- bithiophene-and 2, 2′: 5′, 2 ″-terthiophene-5-carboxylic acids and esters which is based on thiophene ring closure in the Fiesselmann reaction. Using this method, derivatives containing a long alkyl chain with or without an end functional group or an aryl substituent can be conveniently prepared.
