実験手順
A solution of 2,3,4,5-tetraphenylcyclopentadienone (4) (Morgenroth et al, Tetrahedron 1997, 53, 15349) (1.14 g, 2.96 mmol) and (3) (354 mg, 1.98 mmol) in diphenyl ether (3 mL) was deoxygenated and heated at 210° C. under argon for 3 hours. The reaction mixture was purified by column chromatography over silica using a dichloromethane/light petroleum mixture (1:1) as eluent to give (5) (988 mg, 93%).
