In the presence of traces of acidic materials, Diels-Alder condensation of ethylene and cyclohexadiene-1,3 gives, besides the expected bicyclo[2,2,2]octene-2, the isomeric bicyclo[3,2,1] octene-2; the latter is formed through acid-catalysed rearrangement. Its structure was proved among other things by stepwise oxidative degradation to cyclopentane-cis-1,3-dicarboxylic acid.
在痕量酸性物质的存在下,乙烯和环己二烯-1,3的狄尔斯-阿尔德缩合反应除了预期的双环[2,2,2]辛烯-2外,还提供了异构的双环[3,2,1]辛烯- 2; 后者是通过酸催化的重排形成的。通过逐步氧化降解为环戊烷-顺-1,3-二羧酸证明了其结构。
