  Application of Zirconacyclopentadienes (Metalla-heterocycles) and Cross-Coupling for the Convenient Preparative Method of 6,13-Disubstituted Pentacene

  摘要：

  Iodination of zirconacyclopentadiene derivative gave diiododiene derivative. The product was lithiated with t-BuLi and treated with diiodonaphthalene successively to afford 6,13-bis(trimethylsilyl)-5,14-dihydropentacene. A 6,13-diiodo-5,14-dihydropentacene was synthesized by iodination of 6,13-bis(trimethylsilyl)-5,14-dihydropentacene with ICl. This diiododihydropentacene was used for the introduction of substituent at 6 and 13 positions by the cross-coupling reactions with Pd catalyst. After aromatization by a combination of DDQ and gamma-terpinene or triethylamine, 6,13-disubstituted pentacene derivatives were synthesized.
