Photolysis of 4-diazo-1,1,1,2,2,3,3-heptafluoropentane gives heptafluoropropyl(methyl)carbene, in which migration of hydrogen takes place to give 3,3,4,4,5,5,5-heptafluoropent-1-ene in high yield. Migration of fluorine or of the pentafluoroethyl group is not observed. The photolysis of 3-diazo-1,1,2,2-tetrafluoropropane gives the corresponding carbene in which migration of the difluoromethyl group
4-重氮-1,1,1,2,2,3,3-七氟戊烷的光解产生七氟丙基(甲基)卡宾,其中发生氢的迁移产生3,3,4,4,5,5,5 -七氟戊-1-烯的高收率。没有观察到氟或五氟乙基的迁移。3-重氮-1,1,2,2-四氟丙烷的光解反应得到相应的卡宾,其中二氟甲基的迁移是主要反应;据信其他次要产物是由处于激发态的环丙烷产生的,该环丙烷是通过插入γ- CH键形成的。
