[Figure not available: see fulltext.] The reaction of bromosuccinimide with esters of 3-substituted 2,2'-bithiophene-5-carboxylic acids was used to obtain their 5'-bromo derivatives, which were further converted to esters of 3,3'''-disubstituted 2,2':5',2

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.
