concerted addition in which the central and side bonds are cleaved simultaneously. MNDO calculations support such a pathway and suggest that endo attack on the bicyclobutane is preferred to exo. Reaction of the same two carbenes with quadricyclane gives substituted derivatives of the exo-tricyclo[3.2.1.02,4]oct-6-ene system. Although these products rearrange further under the conditions of reaction and/or
二碳甲氧基卡宾和二氯卡宾以这样一种方式加成到1,2,2-三甲基双环[1.1.0]丁烷中,以致于一致地加成,其中中央键和侧键被同时裂解。MNDO计算支持这样的途径,并建议内的bicyclobutane攻击最好外型。相同的两个碳烯与四环烷的反应得到外三环[3.2.1.0 2,4 ] oct-6-ene系统的取代衍生物。尽管这些产物在反应和/或分析条件下会进一步重排,但可以证明它们是主要产物。建议四环烷与卡宾以一致的方式反应。
