摘要: Bis-2,5-dimethylene-2,5-dihydrothiophenes have been generated in the gas-phase by flash vacuum pyrolysis (FVP) of diester precursors. These thiophene-based bis-(p-quinodimethanes) are shown to undergo reactions leading macrocycles. The conversions consistent with a mechanism involving cyclic diradical intermediates followed disproportionation radical centers.
