Abstract
(Chemical Equation Presented) Nonaromatic stable polyenes are obtained by dioxygenation of oligothiophenes using HOF·CH3CN prepared in situ by passing F2 through aqueous acetonitrile (see scheme). These fully S,S-dioxygenated derivatives have a considerably smaller HOMO-LUMO gap than the parent compounds; furthermore, in the solid state they tend to form favorable π-π stacking interactions, unlike most non-oxidized oligothiophenes which adopt the "herringbone" motif.
