New electron donors 11a-c bearing only one 1,3-dithiole ring monocation exhibit butterfly-shaped non-planar structures, the dication is fully aromatic and consists of a closed-shell, conjugated with an acene backbone have been synthesized by Wittig-Horner reactions from 7H-benz [d,e]anthracen-7-sing
The effect of different factors (pK a of the base, nature of the counterion and dissociation of the ion pairs) on the course of the base-induced rearrangement of 1,4-dithiins to 1,3-dithiole derivatives is discussed. Ab initio calculations account for the driving force of these isomerisations.
