p-benzoquinone-TTF-p-benzoquinone triad with malononitrile under different experimental conditions were investigated. In order to avoid the well-known Michael 1,4-addition onto the quinone moiety, cyclopentadiene or cyclohexadiene units were incorporated as protecting groups through [4+2] Diels–Alder cycloadditions. On the one hand, aromatization leading to fused 2-thioxo-1,3-dithiole-hydroquinones
