The occurrence of a structurally degenerate Cope rearrangement which proceeds rapidly at room temperature is revealed by the examination, at varying temperatures, of the N.M.R. spectrum of bicyclo[5.1.0]octa-2,5-diene (I). This molecule is made by the cyclopropanation of cycloheptatriene in the 3, 4 position according to Gaspar-Roth. Its structure is assigned by virtue of its conversion to bicyclo[5
通过在不同温度下检查双环[5.1.0] octa-2,5-二烯(I)的NMR光谱可知,发生了在室温下迅速进行的结构简并的Cope重排。根据Gaspar-Roth,该分子是由环庚三烯在3、4位的环丙烷化反应制得的。其结构是由于其在催化氢化作用下转化为双环[5.1.0]辛烷和未能吸收λ> 210mμ的紫外光而被指定的。
