  decomposition (kd) for a series of exo‐7‐alkylbicyclo[3.2.0]hept‐2‐enes are relatively invariant. For the alkyl substituents ethyl, propyl, butyl, isopropyl, and t‐butyl, the ratio of the rate constant for [1,3] sigmatropic rearrangement to the rate constant for fragmentation, k13/kf, is significantly lower than k13/kf = 150 observed for exo‐7‐methylbicyclo[3.2.0]hept‐2‐ene. Regardless of the size and mass of

  一系列exo -7-烷基双环[3.2.0]庚-2-烯的整体分解速率常数（k d）相对不变。对于烷基取代基乙基，丙基，丁基，异丙基和叔丁基，[1,3]σ重排的速率常数与断裂速率常数的比率k 13 / k f明显低于k 13 / k f  = 150，对于exo -7-甲基双环[3.2.0]庚-2-烯。无论烷基的大小和质量如何，[1,3]碳迁移的立体选择性在表面转化率80％至89％时都相当稳定（si），这与角动量守恒相符，但与轨道对称性守恒相符。总体结果与Carpenter和合作者普遍支持[1,3]σ重排的“动态匹配”现象相对应。
