The reaction of perfluoro-1,2-dichlorocyclobutene with t-butyllithium leads to replacement of Cl by Li. The lithio derivative was stable to −30°C and reaction with trimethylsilyl chloride gave perfluoro-1-chloro-2-trimethylsilylcyclobutene. The reaction of the latter with t-butyllithium leads to dehalogenation and the addition of t-butyl to form a dimeric compound. The reaction of 1-chloro-2,2,3,3
全氟1,2-二氯环丁烯与叔丁基锂的反应导致Cl被Li取代。锂硫基衍生物在-30℃下稳定,并与三甲基甲硅烷基氯反应,得到全氟-1-氯-2-三甲基甲硅烷基环丁烯。后者与叔丁基锂的反应导致脱卤和添加叔丁基以形成二聚化合物。1-氯-2,2,3,3-四氟环丁烯与苯基锂反应,然后用氘氧化处理,得到全氟-1-苯基环丁烯-2-d 1,表明全氟环丁炔可能是中间体。
