Abstract

Novel electron acceptors bearing a heteroquinonoid system, 5, 5′-bis (dicyanomethylene)- 5, 5′-dihydro-Δ 2, 2′-bithiophene, its 3, 3′-dichloro, 3, 3′-dibromo, and 3, 3′, 4, 4′- tetrabromo derivatives, and 5, 5 ″-bis (dicyanomethylene) 5, 5 ″-dihydro-Δ 2, 2′: 5′, 2 ″- terthiophene were synthesized by the action of tetracyanoethylene oxide or by Pd (0)- catalyzed substitution reactions with sodium dicyanomethanide on the corresponding α, α ...
