The sequential palladium‐catalyzed intermolecular direct arylation, bromination followed by intramolecular direct arylation allowed the synthesis of phenanthro[9,10‐b]thiophenes, phenanthro[9,10‐b]thiazoles, acenaphtho[1,2‐d]thiophenes and acenaphtho[1,2‐d]thiazoles in only three steps.
顺序的钯催化的分子间直接芳基化,溴化反应以及分子内直接芳基化使邻菲并[9,10- b ]噻吩,菲并[9,10- b ]噻唑,[1,2- d ]噻吩和的合成成为可能。[1,2- d ]噻唑仅需三个步骤。
