ABSTRACT This paper describes an efficient method for the synthesis of bis(2,2′-bithienyl)methanes from 2,2′-bithienyl. In one case when the method gave an unexpected result, the product was determined by X-ray crystallography.

methane types have been synthesized in a facile two-step synthesis. The resulting bis- and tris-thiophene methanes readily react with oxygen both as solids and in solution to yield stable radicals. The formed radicals, which were investigated using electron paramagnetic resonance (EPR), were found to be residing on the central carbons of the bis- and tris-thiophene methanes.
