diacetylethylene to give substituted bicyclooctadienes as Diels–Alder adducts. Treatment of these with phosphorus pentasulfide gives derivatives of benzenonaphtho[c]thiophenes, which are thiophene analogues of triptycene. Reaction of the anthracenes with dibenzoylacetylene gave substituted bicyclooctatrienes, which on treatment with phosphorus pentasulfide gave inseparable mixtures of the benzenonaphtho[c]thiophenes
多种蒽与二苯甲酰乙烯和二乙酰乙烯反应生成取代的双环辛二烯作为 Diels-Alder 加合物。用五硫化二磷处理这些得到苯并萘并[c]噻吩的衍生物,它们是三苯乙烯的噻吩类似物。蒽与二苯甲酰乙炔的反应得到取代的双环辛三烯,用五硫化二磷处理得到苯并萘并[c]噻吩和苯并萘并[c]-呋喃的不可分离的混合物。噻吩的逆狄尔斯-阿尔德反应的尝试未成功。
