Difluorocarbene reacts with 1,2,2-trimethylbicyclo [1.1.0] butane to give the product of two bond cleavage, 1,1-difluoro-3,3,4-trimethyl-1,4-pentadiene in 3% yield. Bicyclo [2.1.0]pentane is even less reactive, yielding 1,1-difluorohexa-1,5-diene in ca. 0.5% yield. Bicyclo [3.1.0] hexane does not react with difluorocarbene. Theoretical descriptions of these reactions are discussed.
二氟卡宾与1,2,2-三甲基双环[1.1.0]丁烷反应,以3%的收率得到两个键断裂的产物1,1-二氟-3,3,4-三甲基-1,4-戊二烯。双环[2.1.0]戊烷的反应性甚至更低,在大约1小时内产生1,1-二氟六-1,5-二烯。收率0.5%。双环[3.1.0]己烷不与二氟卡宾反应。讨论了这些反应的理论描述。
