The study of a side product of the aerial dithiolene oxidation allowed the rational and efficient synthesis of a sulfur rich electron acceptor, (E)-3,3′-diethyl-5,5′-bithiazolidinylidene-2,4,2′,4′-tetrathione, that presents easily accessible redox states and forms with decamethylferrocene a charge transfer salt exhibiting ferromagnetic coupling.

Among different approaches, the thermal treatment of the fused bicycle involving a dithiole-2-one ring is the most efficient one and opens access to a variety of π-conjugated electron acceptors.
Novel π-electron acceptors are still highly desirable for the formation of conductingsalts or as n-dopable semiconductors. We describe here two synthetic approaches to substitute a dicyanovinylidene group, CC(CN)2 to a thioketone (CS) in the recently described DEBTTT acceptor where DEBTTT stands for (E)-3,3′-diethyl-5,5′-bithiazolidinylidene-2,4,2′,4′-tetrathione.
