Abstract

Two heterocyclic compounds based on the thieno [3, 4-c] thiophene structure with four aryl substituents were prepared and their behavior in electrooxidation studied. These tetraarylthieno [3, 4-c] thiophenes were synthesized in three steps starting from 1, 3- dibenzoylmethane in the case of 1, 3, 4, 6-tetraphenyl-2 u 4 i 2-thieno [3, 4-c] thiophene 1a and from 1, 3-bis (4'-methoxyphenyl) propane-1, 3-dione in the case of 1, 3, 4, 6-tetrakis (4 ...
