Abstract
AbstractTriphenylphosphorane reagents 8 react with 1,3,5‐cycloheptatriene‐1,6‐dicarbaldehyde (2) under acidic as well as basic conditions to produce 1,6‐methano[10]annulene‐3,4‐dicarboximides 1 in moderate ‐to‐ good yields. The reagents 8 react with 3,4‐arene‐annulated 1,3,5‐cycloheptatriene‐1,6‐dicarbaldehydes 9, 10, and 11 to afford only the Wittig condensation products under acidic conditions but produce the arene‐annulated annulenedicarboximides under basic conditions. The structures of some of the dicarboximides and the intermediate Wittig condensation products were determined by X‐ray structural analysis. The emission properties of the dicarboximides were also studied.
