Base-induced elimination of dichlorocarbene adducts 2 to 9-alkoxyphen threnes 1 leads to furans 6, presumably via cyclopropenes 3 which undergo rearrangement to vinylcarbenes 4 and CH insertion. By the same sequence, the 9-substituted alkylphenanthrene adduct 10 and 14 afford cyclopentadienes 11 and 15. Carbene adducts of simple enol ethers, however, react differently and give preferentially 2-chloroalken-2-ones
碱诱导的二氯卡宾加成物2至9-烷氧基苯并菲1的消除导致呋喃6,大概是通过环丙烯3进行的,该环丙烯3进行了重排为乙烯基卡宾4和CH插入。按照相同的顺序,9-取代的烷基菲加合物10和14提供环戊二烯11和15。但是,简单的烯醇醚的碳烯加成物反应不同,并优先生成2-氯烯-2-酮。
