cis- and trans-1,1,4,4-tetramethylcyclododec-8-ene pair; large differences in the relative stabilities and hydrogenation enthalpies have been found. The results are discussed in conformational terms and possible conformations of the cis- and trans-cyclododecenes are considered.
已经确定了八种位置和顺式-反式异构体1,1,4,4-四甲基环十二烯体系的平衡。已经测量了顺式和反式-1,1,4,4-四甲基环十二碳烯-8-烯对的氢化焓;已经发现相对稳定性和氢化焓有很大差异。以构象术语讨论了结果,并考虑了顺式和反式-环十二碳烯的可能构象。
