Attempts to cyclise o-chlorophenyl benzyl ether, sulphide, sulphoxide and sulphone by treatment with KNH2/NH3 were unsuccessful. Similar reaction of 1-(o-chlorophenyl)-2,2-diphenylethane led to amination whereas α-(o-chlorobenzyl)phenylacetic acid gave a dihydrocoumarin. Reaction of 4- and 2-(o-chlorophenethyl)-pyridines, however, afforded products comprising benzisoquinolines and 1-pyridylbenzocyclobutenes
通过用KNH 2 / NH 3处理来环化邻氯苯基苄基醚,硫化物,亚砜和砜的尝试均未成功。1-(邻氯苯基)-2,2-二苯基乙烷的类似反应导致胺化,而α-(邻氯苄基)苯基乙酸产生二氢香豆素。然而,4-和2-(邻氯苯乙基)-吡啶反应,得到包含苯并异喹啉和1-吡啶基苯并环丁烯的产物。
