The title reaction afforded the Diels-Alder adduct 4b,10-ethenobenz [a]azulene (4), while an analogous reaction involving 5,6-dichloroazulene gave the 6,7- and 7,8-dichloro-derivatives of (4). Treatment of (4) with 3,6-di(pyridin-2-yl)-s-tetrazine yielded benz[a]azulene.
标题反应得到狄尔斯-阿尔德加合物4b,10-乙炔联苯[a] azulene(4),而类似的反应涉及5,6-二氯azulene,得到(4)的6,7-和7,8-二氯衍生物。 。用3,6-二(吡啶-2-基)-s-四嗪处理(4)得到苯并[a]]。
