摘要：

Fused bispentacenequinone 2 was synthesized by photocyclization of bispentacenequinone 1. Unusual regioselective Michael addition was observed for 2 when excess aryl Grignard reagent was used. Subsequent acidification and oxidation in air gave diaryl-substituted bispentacenequinone 3. Tetra-aryl-substituted fused bispentacenequinone 4 was obtained from 3 after the second Michael addition followed by oxidation in air.
